KANSAS CITY, Mo. — The Los Angeles Chargers officially ruled out starting right tackle Joe Alt (knee), listing him as inactive a day after downgrading his injury designation from questionable to doubtful.

The move leaves the Chargers without both starting offensive tackles against the two-time reigning Super Bowl champion Kansas City Chiefs, who have won a record eight consecutive AFC West titles, for Sunday afternoon’s game at SoFi Stadium in Inglewood, California.
