Chiefs DE Frank Clark is doubtful for Sunday's game against the Chargers with more hamstring trouble. The Kansas City Star reports that this injury is to the opposite leg from the one he hurt in training camp that kept him out of the season opener. We'll see how long this one keeps him out.

Chiefs EDGE Frank Clark left Saturday's win over the Raiders with a groin injury and did not return. He was ruled out early in the 2nd half. That's generally a bad sign for the severity of an injury. Of course, K.C. was already way up at that point in the game and had no reason to push Clark back into action. The victory also gives him the bye week to heal up before their playoff opener. We'll watch for further details on the injury.

Chiefs DE Frank Clark put in a full practice Wednesday. That's not something he's done much so far this season, including the past 2 weeks. Clark missed both of those games with a hamstring injury. That came on the opposite leg from the one that cost him Week 1 (with another hamstring injury). It looks like Clark is on track to play the Bills this Sunday. We'd rather see him play before getting him back into IDP lineups, though. DL Chris Jones, meanwhile, missed practice with his wrist issue. Unless Jones has suffered a setback, we'd bet on this just being a management thing.

Chiefs DE Frank Clark (hamstring) is inactive for today’s game against the Browns

Chiefs DE Frank Clark is questionable for Sunday's game against the Browns with a hamstring injury. Clark put in just limited practices all week. Don't trust him in your Week 1 IDP lineups, even if he's active.

Chiefs DE Frank Clark was arrested Sunday night in L.A. after police spotted an Uzi (submachine gun) in his car, ESPN's Adam Schefter reports. The situation will certainly get a review under the league's personal-conduct policy. We'll see whether it ultimately costs Clark any games.
