Green Bay Packers offensive tackle Bryan Bulaga has sprained his knee, not torn his ligament, according to coach Mike McCarthy.

"As of right now, we do not fear a major injury," McCarthy said. "That's where it stands. Until we get back and get the scans we'll know better."

Bulaga hurt his left knee. Last year, he suffered a torn anterior cruciate ligament in his left knee and was out for the seaosn.

He got hurt Thursday when Bulaga got knocked into by Seattle Seahawks defensive end Michael Bennett.

Derek Sherrod replaced him and allowed two sacks.

"It changed a couple things," McCarthy said. "We flipped our plan based on what they were doing. We got caught a couple times in some uphill situations as how the protection was set. They got the safety. Hey, that's football."
