TENNIS

NEW YORK - No. 1 Novak Djokovic is into his 26th straight major quarterfinal after a hard-fought victory over Roberto Bautista Agut at the U.S. Open.

Djokovic dropped a set for the first time this tournament, and the 23rd-seeded Spaniard made him work throughout the 6-3, 4-6, 6-4, 6-3 win Sunday night.

Bautista Agut, who has never reached a Grand Slam quarterfinal, was down a break in the second set. But he won the last four games to pull even, running down every shot, ripping big forehands and leaving Djokovic to stomp on his racket in disgust.

The nine-time major champ responded by raising his level to close out the match in four sets. He next faces 18th-seeded Feliciano Lopez.

NEW YORK - Serena Williams is three wins away from completing the first Grand Slam since 1988 after a crisp straight-set victory over young American Madison Keys.

The 21-time major champion had been getting off to slow starts recently but was focused from the beginning Sunday, winning 6-3, 6-3 in just 68 minutes in the fourth round.

She faces sister Venus in the quarterfinals.

The 20-year-old Keys nearly matched Williams booming serve for booming serve but made just enough mistakes. She had 19 unforced errors to just six for Williams, including six double-faults - most of them coming at inopportune times, including match point.

FOOTBALL

FOXBOROUGH, Mass. - Patriots quarterback Tom Brady just wants to move on.

Making his first public comments since the ''Deflategate'' court ruling, Brady said he is focused on preparing for Thursday's game against Pittsburgh. He also recognized his family, friends and Patriots owner Bob Kraft for their support.

''Everything that's happened over the past seven months, obviously I have a lot of personal feelings, but I really don't care to share many of those,'' Brady said Sunday.

''I really care to think about what I need to do going forward. We've got a lot of guys in this locker room who worked really hard to get to this point, and so have I, and I'm excited to be able to go out there and do it.''

Brady's four-game suspension for his role in using underinflated footballs during the AFC championship game was overturned Thursday by a federal judge who criticized NFL Commissioner Roger Goodell for going what he said was ''far beyond'' the investigative conclusions of attorney Ted Wells.

Brady said the NFL's decision to appeal the ruling is ''their choice.''

UNDATED - Tim Tebow is the biggest name among NFL cuts for the second time in three years.

Tebow had seemingly won the No. 3 QB job when Philadelphia traded Matt Barkley to Arizona on Friday.

But coach Chip Kelly cut the unconventional quarterback who showed improved accuracy since his first stint in the NFL.

''We felt Tim has progressed, but we didn't feel he was good enough to be the (No.) 3 right now,'' Kelly said.

Tebow last played in a regular-season game in 2012 with the Jets, who traded for him a day after Peyton Manning went to Denver. The Patriots cut Tebow in 2013 when he failed to win a job as Tom Brady's backup, and Tebow spent last year in the broadcast booth.

Tebow was among more than 700 players cut across the NFL on Saturday as teams trimmed their rosters to 53.

Other quarterbacks who were jettisoned were veterans Matt Cassel (Buffalo), Rex Grossman (Falcons), Christian Ponder (Raiders) and Matt Flynn, who hopes to return to the Jets after Week 1, when his salary wouldn't be guaranteed.

Other notable players whose phones buzzed with that dreaded call to turn in their team-issued tablets included: WR Reggie Wayne (Patriots), CB Will Blackmon (Seahawks), DL Darnell Dockett (49ers), MLB Jameel McClain (Giants), DT Devon Still (Bengals), RB Jonas Gray (Patriots), WR James Jones (Giants), WR Hakeem Nicks (Titans), DE IK Enemkpali (Bills) and K Nick Novak (Chargers).

BASEBALL

MIAMI - Matt Harvey now insists he will pitch in the postseason if the New York Mets get there.

After a two-day uproar over his innings limit this year, Harvey writes Sunday on ''The Players' Tribune'' that he will be ready to participate if the Mets make the playoffs.

He says he is communicating with his doctor, agent Scott Boras and the Mets to come up with a plan that makes him available in October. Harvey says it will be a compromise between doctors and the Mets, and he ''can assure everyone that we're all on the same page.''

The right-hander, in his first season back from Tommy John surgery, says he understands the risks of going beyond 180 innings this year.

New York holds a four-game lead in the NL East over the Nationals heading into a crucial three-game series between the teams beginning Monday in Washington.

Harvey is scheduled to start Tuesday night.

COLLEGE FOOTBALL

LEXINGTON, Ky. - University of Kentucky officials continue to investigate the crash of a student's drone into a section of Commonwealth Stadium before Saturday night's football game against Louisiana-Lafayette.

The school has not released the student's name, and spokesman Jay Blanton said Sunday a decision on any discipline isn't likely before Tuesday as university police determine what violations occurred.

The subject of drone use is a moving target, so to speak, as federal and local officials examine how to regulate them with growing personal and commercial use.

Kentucky does not have a written policy banning the unmanned aircraft, but as the school studies the issue Blanton said drones aren't allowed on campus and added, ''it's pretty clear that they're not allowed around the stadium on game day.''

The drone flew as skydivers parachuted onto the field with American flags before the Wildcats' 40-33 victory over the Ragin' Cajuns. It crashed into the southwest corner of the newly remodeled stadium at the suite level. There were no injuries or damage to the stadium.

Blanton said the school is applying for an exemption to allow limited flights for research and other allowable uses, but recommendations aren't expected until later this semester.

SOUTH BEND, Ind. - Coach Brian Kelly says running back Tarean Folston is out for the season after tearing a ligament in his right knee in No. 11 Notre Dame's 38-3 victory over Texas.

Kelly said Sunday morning that Folston tore his medial collateral ligament and will have surgery later this week.

Folston was injured on his third carry, and jogged off the field with a limp. The 5-foot-9, 214-pound junior led the Irish in rushing last season with 889 yards on 175 carries and was expected to get even more chances this season as the only experienced back.

The loss could be a big blow to the Fighting Irish. Their second-leading rusher from last season, Greg Bryant, left school after being ruled academically ineligible. That leaves one-time wide receiver C.J. Prosise as the top running back. He ran for 98 yards on 20 carries against Texas.

OLYMPICS

TOKYO - Zaha Hadid Architects, the company whose stadium design for the Tokyo 2020 Olympics was chosen and later scrapped, says it is teaming up with major Japanese design and engineering company Nikken Sekkei in a bid to regain the project.

Prime Minister Shinzo Abe announced in July that Hadid's design had been dropped as too costly, seeking to quiet an outcry over the futuristic, huge stadium blueprint.

The government has begun accepting new bids for the project, with a cost ceiling of 155 billion yen ($1.3 billion). Hadid's earlier project had been estimated to cost over 250 billion yen ($2 billion).

The two companies said Monday they would offer ''the most cost-effective delivery plan'' to ensure the stadium is ready in time for the 2020 Olympics.

MARBLE FALLS, Texas - A San Antonio school district has suspended two football players from the team after one of them ran into the back of a referee watching a play and the other dove into the official, the district's athletic director said Sunday.

Northside Independent School District athletic director Stan Laing told KENS5-TV (http://bit.ly/1Kzcx7I ) that the players had been suspended because of the incident Friday, which he called ''disturbing'' and ''inexcusable.''

Video showed the referee watching the play, and his head snapping back when he is leveled from behind. The other player then dove on top of him. The team from John Jay High School in San Antonio was playing Marble Falls High School in Marble Falls, located about 90 miles north of San Antonio.

Before the referee was hit, two Jay players had been ejected on separate plays.

Pascual Gonzalez, a spokesman for the Northside Independent School District, told The Associated Press earlier Sunday that the district would hear from game officials, coaches and students during an upcoming due process hearing.

''It is not the good sportsmanlike behavior that we teach students,'' he said.
