Wes Welker has not been medically cleared to return to practice, andDenver Broncos coach John Fox said only that the wide receiver is "day-to-day.'' Welker, who suffered a concussion just before halftime of the Broncos' victory over theTennessee Titans on Dec. 8, was held out of Thursday night's loss to the San Diego Chargers. Welker also suffered a concussion in the Broncos' Nov. 17 win over the Kansas City Chiefs. Before he can play in a game, Welker would have to be declared symptom-free by both the Broncos' medical staff and a designated independent physician who has been approved by the NFL and the players' association. Welker would then have to proceed through multiple days of limited activity before he could return to practice on a limited basis. Source: ESPN
