A few minutes later, quarterback Jason Campbell was released.
They combined to start 13 games in 2013, winning one.
Weeden was 0-5 as a starter last season and 5-10 in his two years. He was a first-round draft pick in 2012.
“First and foremost, the Browns would like to thank Brandon and his agent for being true professionals,” new general manager Ray Farmer said in the release announcing the move. “The circumstances in which he found himself were not easy for him or the team. After discussions with Brandon and his agent, we’d like to give him the ability to pursue other opportunities.”
Weeden, 30, began 2013 as the starter, injured his thumb in Week 2 and was replaced by Brian Hoyer. Weeden returned to the lineup after Hoyer suffered a torn anterior cruciate ligament, but lost the job again after a bad six quarters in losses to Detroit and Green Bay.
Weeden finished the year completing 52.8 percent with nine touchdowns, nine interceptions and a 70.3 rating. He had a 71.8 rating in his two years with 23 touchdowns and 26 interceptions.
Campbell was due a $250,000 roster bonus Thursday, precipitating his release.
“Right now I’m just anxious to know what the Browns are going to do,” Campbell told ESPN earlier in the day. “If I’m going to be back, I’d like to be able to prepare for that. If I’m not returning, my agent can get to work on my next move.”
Campbell started eight games last season, winning one. His confidence crashed after a heartbreaking loss to New England, and the coaching staff lost faith in him.
Campbell, 32, completed 56.8 percent for 2,015 yards, 11 touchdowns, eight interceptions and a 76.9 rating.
The two-year contract he signed last year called for a $3 million salary in 2014.
“We appreciate Jason’s contributions to the Browns in 2013,” Farmer said. “He’s a respected veteran player in this league. We felt like at this time, early in the free-agency period, we would give him a better opportunity to move forward. We wish Jason the best in his future endeavors.”
