FLOWERY BRANCH, Ga. (AP) — The Atlanta Falcons have signed Rex Grossman to compete for the backup quarterback job behind Matt Ryan.

Grossman, who hasn't thrown an NFL pass since 2011, helped Chicago go 13-3 in 2006 and reach the Super Bowl. He's 26-22 in his career since getting drafted in the first round 12 years ago.

He joins T.J. Yates and Sean Renfree in the competition for the No. 2 QB role. Grossman played under Falcons offensive coordinator Kyle Shanahan and went 6-10 in two seasons. He spent 2010-2013 with the Redskins.

Atlanta waived injured running back Evan Royster to make room for the 35-year-old Grossman on the roster.
