Colts RB Joseph Addai suffers concussion against Packers in 3rd quarter

Indianapolis Colts starting running back Joseph Addai sustained a concussion midway through the third quarter of Thursday night's exhibition game with the Green Bay Packers.

"It's nothing," Addai said after the game. "I was fine. I just got a little dizzy, but I was cool."

Addai was hurt making a tackle of Robert Francois after Francois scooped up a fumble by Peyton Manning when the quarterback was hit stepping up in the pocket.

Addai ran down Francois, but came down hard making the tackle at the Colts 2. He described his injury more of just getting the wind knocked out of him.

"I just had to catch my breath. I was fine," Addai said. "If I needed to go back in, I could've, I was straight."

Addai walked slowly to a cooler and sat with his head in a towel while trainers spoke with him. After a few minutes, he paced the far end of the Colts' sideline watching the action and later was talking with Adam Vinatieri and Clint Session.

The Colts had kept their starters in past halftime, while the Packers pulled most of their regulars at the break.
