Injury-riddled Chargers turning to rookies to help give their season some life

The rash of offensive line injuries that were a scourge for the Chargers last season have returned, complicating an already dismal situation for a team seeking its first win of the season Sunday against the Denver Broncos at SoFi Stadium. Left guard Kayode Awosika (fibula) and his replacement, Trey Pipkins III (knee), are out. Right tackle Joe Alt is out with a neck injury and left tackle Rashawn Slater was placed on injured reserve after undergoing surgery for a high-ankle sprain. Reserve guard Trevor Penning also won't play because of a concussion.
