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

Tebow had seemingly won the No. 3 quarterback 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.

He completed 21 of 56 passes this preseason for 286 yards, two TDs and an interception. He also ran for 82 yards and a score.

Tebow was trying to make an NFL comeback after a two-year absence. The New England Patriots cut him in 2013 after his failed attempt to back up Tom Brady following time with Broncos and the Jets.

Other notable players whose phones buzzed with that dreaded call to turn in their team-issued tablets were Cincinnati defensive tackle Devon Still and Broncos cornerback Tony Carter.

Still tweeted thanks to the Bengals and the city after he was released. Still's 5-year-old daughter, Leah, has overcome cancer in the past year. The second-round pick from 2012 also was released last year, but the Bengals offered him a chance to stay on the practice squad to keep his medical coverage for his daughter. He was eventually added to the roster and played in 12 games.

''Have nothing but love for the Bengals organization and the city of Cincinnati. Both helped...'' he tweeted.

The Bengals also put linebacker Vontaze Burfict on an injury list. He'll be eligible to return after six weeks. Burfict is recovering from two knee operations.

In Denver, Carter, a seventh-year cornerback, and fourth-year linebacker Steven Johnson both tweeted that they'd been cut, as did Ben Garland, who was the starting left guard heading into training camp. Carter has been bothered by a pulled hamstring since Aug. 17.

In Pittsburgh, Doug Legursky's return was short-lived. The Steelers signed him as a potential replacement for injured All-Pro center Maurkice Pouncey. Legursky started 17 games for the Steelers during his first stint in Pittsburgh from 2009-12, including the 2011 Super Bowl against Green Bay when Pouncey was hurt.
