Jermichael Finley has concussion

CINCINNATI -- For the second straight week, the Green Bay Packers lost one of their top offensive playmakers to a concussion.

Jermichael Finley left Sunday's loss to the Cincinnati Bengals in the first quarter after getting drilled by safety George Iloka, who appeared to lead with his shoulder and hit the Packers tight end in the head while breaking up a third-and-11 play.

There was no penalty called for a hit on a defenseless player.

Finley initially tried to get up after the hit but then went down to one knee, which brought out the Packers' medical staff. Finley was taken to the locker room for evaluation and was ruled out for the rest of the game.

In Week 2, the Packers lost running back Eddie Lacy to a concussion after Washington Redskins safety Brandon Meriweather's helmet-to-helmet hit. Meriweather wasn't penalized but was fined $42,000 for the hit on Lacy, who was inactive for Sunday's game.

Finley wasn't the only Packers player hobbled.

Linebacker Clay Matthews tweaked his hamstring while forcing his second fumble of the second quarter. He did not return.

"I'll be good," Matthews said. "I think today was more of a preventative measure than anything. I felt like I could go back out there, but we had to be smart with this, especially going into a bye week. I don't see myself missing any time. We've got Detroit coming back and I'll be out there."

Also, running back James Starks injured his knee in the first half.
