COSTA MESA, Calif. (AP) — The Los Angeles Chargers will be missing at least two starters when they visit the Buffalo Bills on Sunday.

Offensive tackle Joe Barksdale and defensive end Joey Bosa have not practiced all week and are nursing injuries that could have them out for a while. Barksdale injured his right knee in last Sunday's 38-28 loss to Kansas City and Bosa has a bone bruise in his left foot.

Cornerback Craig Mader, who is used mostly on special teams, is also out due to a hamstring injury.

Wide receiver Travis Benjamin (foot) is questionable. Benjamin did not practice Wednesday or Thursday but was limited on Friday. Coach Anthony Lynn said he is "very optimistic" that the seventh-year receiver will be able to play on Sunday.
