Elgton Jenkins' injury was a big hit for the Green Bay Packers offensive line. The Pro Bowl left guard suffered had an MCL sprain, which will make him miss playing time — he isn't expected to go on the injured reserve, but he has already missed a part of the game against the Atlanta Falcons, the entire game versus the New Orleans Saints, and isn't expected to play on Thursday against the Detroit Lions.
So far, the Packers coaching staff decision has been to replace Jenkins with Royce Newman, who has significant starting experience in the NFL. However, his performance hasn't been good whatsoever.
