New York Giants running back Andre Brown was diagnosed with a concussion, head coach Tom Coughlin confirmed Monday. Brown, who has the second most carriers on the team, was ruled out of Sunday's 41-27 victory over the visiting Cleveland Browns after suffering the injury on a first-quarter kickoff return.
It's unclear if the head injury will keep him out of the Giants' Week 6 contest with the visiting San Francisco 49ers (4:25 p.m. ET on FOX).
In the middle of Sunday's win, Brown tweeted that "everything was OK." The tweet has since been deleted.
So far this season, Brown has rushed for 198 yards and scored three touchdowns. The three-year veteran has emerged as a solid short-yardage back for the Giants, who drafted the NC State product in the fourth round of the 2009 NFL Draft. This is Brown's second stint with New York after he was waived following his rookie season.
Brown spent time with the Denver Broncos, Indianapolis Colts and Carolina Panthers before returning to the Giants, who re-signed the tailback to the practice squad in the offseason.
