The roster move to make room for the speedster is not yet known, but it seems likely the team will cut fifth receiver Derek Hagan.
Graham was a 2012 third-rounder out of NC State. In two seasons he caught 54 passes for 683 yards and three touchdowns.
I asked Greg Cosell of NFL Films about Graham.
"Vertical speed guy, nothing more,” Cosell said. “He can run."
