CLEVELAND - Browns quarterback Brandon Weeden has been diagnosed with a concussion following the Browns' loss to the Jaguars.
A team spokesperson said Weeden reported symptoms after the game.
There was no word on when he may have suffered the concussion.
Weeden was not permitted to talk to the media due to the NFL's concussion protocol.
He played all four quarters, never exiting the game, and going 24-40 for 370 yards passing, three touchdowns and two interceptions, as well as a fumble.
Those three turnovers in the closing stages of the first half led to 13 Jaguars points.
Weeden started in place of Jason Campbell, who missed Sunday's game due to a concussion suffered on a hit by the Steelers' William Gay in Week 12.
The Browns signed quarterback Alex Tanney off the Cowboys' practice squad to backup Weeden.
Weeden, who began the season as the Browns' starter, was forced to the bench by a thumb injury suffered in the fourth quarter of a Week 2 loss to the Ravens. Brian Hoyer started Week 3 and took hold of the job until he went out with a season-ending knee injury. Weeden played in relief of Hoyer, helping the Browns to a Week 5 victory over the Bills.
After Weeden struggled in two subsequent starts against the Lions and Packers, Campbell was given a shot, until injury knocked him out of action too.
