Dunta Robinson injury: Falcons CB has a concussion

Atlanta Falcons cornerback Dunta Robinson has a concussion, according to Mike Florio of Pro Football Talk.

Robinson left Sunday's game in the first quarter against the Tampa Bay Buccaneers. The Falcons lost, 22-17, in a game that didn't effect their playoff seeding:

"It was called a 'head injury' at the time, with no updates provided until coach Mike Smith met with the media on Monday. Smith acknowledged in response to reporters' questions that Robinson is 'in the concussion protocol,' which necessarily means that he has suffered a concussion.

Robinson has suffered concussions in the past, including once in 2010. Smith said he expects Robinson to play in the Falcons' first playoff game next weekend, against an opponent to be determined.

The first-round pick in the 2004 NFL Draft started 15 of 16 games for the Falcons this season. He finished the season with 67 tackles, eight pass deflections and an interception. He is in his third season with the Falcons after spending his first six with the Houston Texans.

Atlanta will play either the Washington Redskins, Minnesota Vikings or the Seattle Seahawks next weekend in the divisional round. The Falcons have home-field advantage throughout the playoffs.
