Backup A.J. Feeley was waived Monday by the San Diego Chargers, whose remaining three quarterbacks have zero NFL starts and one touchdown pass among them. The Chargers also released two draft picks and learned they'll be without left tackle Roman Oben for the season's first six weeks. As it is, the Chargers are currently down to fourth-string left tackle Cory Lekkerkerker as they try to keep first-year starting quarterback Philip Rivers in one piece. Rivers' backups are both rookies.
