PITTSBURGH (AP) - Martavis Bryant's blossoming NFL career took another significant hit when the NFL suspended the talented but troubled wide receiver for at least one year following another violation of the league's substance abuse policy.

This is the second league-mandated discipline for Bryant. The 24-year-old sat out the first four games last season following a violation during the offseason.

Bryant caught 50 passes for 765 yards and six touchdowns when he returned in Week 6 and was dynamic in the playoffs.

GREEN BAY, Wis. (AP) - Defensive tackle B.J. Raji said he is taking a hiatus from the NFL and will not play in 2016 following seven seasons with the Green Bay Packers.

Raji said in a statement that he made the decision after hours of conversation with family members and mentors. He did not rule out a return to the field.

The statement was provided by Raji's agents.

Raji was a free agent after having a good season in 2015 with 22 tackles in 15 regular-season games.

OWINGS MILLS, Md. (AP) - The Baltimore Ravens and safety Eric Weddle agreed to terms on a four-year contract.

An All-Pro in 2011 and 2014, Weddle has spent his entire nine-year career with the San Diego Chargers. But that ended in an ugly manner last season.

In 137 career games, he has 813 tackles and 19 interceptions - three of which were returned for touchdowns.

WOMEN'S COLLEGE BASKETBALL

UConn's run at an unprecedented fourth straight national championship will begin at home.

The Huskies were the top overall seed in the women's NCAA Tournament. UConn (32-0) potentially won't have to leave the state until the Final Four which is in Indianapolis this year. The Huskies are in the Bridgeport Regional.

Joining them as the other No. 1 seeds are South Carolina, Notre Dame and Baylor. UConn has already beaten the Gamecocks and Irish this season. The Huskies would face Baylor on April 3 in the national semifinals if both teams advance that far.

UConn and Tennessee have both won three straight women's titles, but no women's team has four consecutive championships. The UCLA men's team won seven in a row. A title this year would give UConn coach Geno Auriemma 11 in his career, breaking a tie with celebrated UCLA men's coach John Wooden.

HARTFORD, Conn. (AP) - Former Yale basketball captain Jack Montague was expelled over a sexual assault allegation and plans to sue the school, his attorney said.

Attorney Max Stern issued a statement saying Montague had a relationship with the woman. He said the dispute is about the last of four sexual encounters, occurring in October 2014.

The lawyer said the woman claims she didn't consent to the sex but Montague said she did and also asserts she later came back to his room to spend the night.

Stern said a Title IX official filed a complaint on the woman's behalf on Nov. 18, a university panel ruled against him and the provost upheld that ruling. Montague was expelled on Feb. 10.

Stern said Montague participated in the hearing process.

Yale went 7-1 in his absence, finishing 22-6 and winning the Ivy League championship with a 13-1 league record. The team plays Baylor on Thursday in the first round of the NCAA Tournament, the school's first appearance in the event since 1962.
