Packers' Mike McCarthy confirms 'significant' knee injury for Andy Mulumba
Green Bay Packers head coach Mike McCarthy announced that linebacker Andy Mulumba suffered a knee injury in Week 2.
McCarthy did not announce a timetable for his return.
Mulumba recorded 30 tackles last season, when he also suffered an ankle injury. He'll be missed on a Packers' defense that's had lapses in the first two weeks.
