Matthews is being evaluated by the Packers' team doctors Monday for an undisclosed injury that is not believed to be serious, ESPN's Rob Demovsky reports.

EDGE Analysis

Matthews made a brief exit early in Sunday night's game against the Vikings, and although the reason for that trip to the sideline was never revealed, his visit with Green Bay's doctors Monday is presumably related. In any case, coach Mike McCarthy doesn't think Matthews' situation is serious. Regardless, his potential inclusion on the Packers' practice report this week could prove worth a look for clarification.
