LB Brad Jones is the Packers' latest injury

Man alive. If you want to know why the Green Bay Packers suddenly added three new linebackers this week, well, you might not want to hear this. Another starter has suffered a serious injury.

Linebacker Brad Jones, who had perhaps his best game of the season last Sunday against the Minnesota Vikings, has what Packers coach Mike McCarthy termed a significant shoulder injury that will require surgery at some point. Jones is out for Sunday's game at the New York Jets, but it's not yet clear if he will miss the remainder of the season or if he will try to put off surgery.

Already, two linebackers -- Nick Barnett and Brady Poppinga -- are among the nine players the Packers have on injured reserve. As a result, the Packers signed claimed Diyral Briggs off waivers from Denver and signed free agents Matt Wilhelm and Erik Walden. All three will focus on special teams, while the Packers' presumed starters will be Clay Matthews, A.J. Hawk, Desmond Bishop and Frank Zombo.

I don't even know what to say anymore about the Packers' injury situation. Jones has had trouble staying on the field all season, but Sunday night he had six tackles and put the hit on Vikings quarterback Brett Favre that not only caused an interception but also resulted in two left foot fractures. The Packers' motto for this season needs to be "Next man up." Either that or, "Mercy."
