Former NFL All-Pro Jimmy Graham was hit by a car during a bike ride earlier this week ... and, according to his buddy and former Green Bay Packers linebacker A.J. Hawk, the ex-tight end suffered a gnarly gash on his leg.
Hawk said on Wednesday's 'Pat McAfee Show' the terrifying incident went down in South Florida earlier this week ... when Graham was cruising on two wheels on Miami roadways.
Hawk revealed that during the ride, a car suddenly turned left ... and smashed into the former New Orleans Saints Pro Bowler.
