Packers' Clay Matthews suffers groin injury in Sunday's game vs. Lions, did not return

Green Bay Packers linebacker Clay Matthews left Sunday's loss to the Detroit Lions with a groin injury and did not return to action.

Matthews' on-field impact is undeniable, but he has certainly had his share of struggles with injuries in the past few seasons.

The Packers will hope their star pass rusher will be available for next Sunday's key divisional game against the Chicago Bears.
