Jets' Abraham will miss 4-6 weeks because of sprained knee

All-Pro defensive end John Abraham of the New York Jets sprained his left knee in practice Saturday, but plans to be in the lineup when the team opens its season in less than five weeks.

An MRI examination Monday revealed a second-degree sprain of the medial collateral ligament, and the team estimated he will be out four to six weeks.

Abraham thinks otherwise.

"I'm confident I'll be back before the first game in Buffalo," Abraham said. "I'm shooting for the last preseason game or the first game. "I feel I'll be ready in four weeks."
