GLENDALE, Ariz. -- Green Bay starting wide receiver Greg Jennings, who left Friday night's game at Arizona early in the first quarter after taking a blow to the head, said he suffered a concussion, according to the Green Bay Press-Gazette.
"Got hit, got a concussion," Jennings told the newspaper on his way out of the locker room. "But I'm good now."
Jennings, who didn't require medical tests for the injury and remained on the sideline, was hurt when he was sandwiched by Cardinals cornerback Bryant McFadden and safety Aaron Francisco after catching a 25-yard pass from Aaron Rodgers.
Jennings lay on the turf for several minutes before he was able to walk off on his own. He said he briefly lost consciousness.
"Yeah, for a second or two," he said, according to the paper. "It's part of football. I'm good now. Everything's working normal. I called the wife and told her everything's good, and I'm good to go."
The injury came on a game-opening touchdown drive for the Packers. It was the sixth touchdown drive in seven attempts for Green Bay's No. 1 offense in the preseason.
