Allen (knee/tooth) did not practice Thursday.
Wednesday's injury report cited Allen's knee issue as the culprit for his absence from practice. Subsequently, Thursday's report noted a tooth issue as well. In any case, what the team's top pass catcher is able to do Friday will be telling with regard to his status for Sunday's game against the 49ers. With Travis Benjamin still limited by a foot injury, Tyrell Williams and Mike Williams currently profile as the Chargers' healthiest wide receivers.
