The Los Angeles Chargers revealed Wednesday that wide receiver Keenan Allen will miss the team's Thursday Night Football matchup against the Kansas City Chiefs with a hamstring injury. Allen exited the Chargers' game last week in the second quarter and didn't return. Before he exited the game, Allen was having an excellent start to his 2022 season, catching four passes for 66 yards in less than one half. His departure didn't prove too costly for Los Angeles, which went on to win 24-19. If he misses more time, however, his absence could become more apparent. As young quarterback Justin Herbert's favorite target, Allen has given the Chargers' offense stability when he has appeared on the field. Though Herbert has performed well without Allen in the past, he also depends on him heavily when he's available, targeting him at least eight times in all but two games last season. In Allen's absence Week 1, veteran receiver DeAndre Carter filled in and had a productive day, catching three passes for 64 yards and a touchdown. Receiver Joshua Palmer is also expected to have an increased role in the offense without Allen. The Chargers' injury report also indicates that tight end Donald Parham Jr. will also miss the game with a hamstring injury, further damaging Los Angeles' receiving corps. Cornerback J.C. Jackson is questionable with an ankle injury. This is not the best week for Los Angeles to compete with a depleted roster, as they will have to take on their division rivals, the Kansas City Chiefs, on primetime television. In Week 1, the Chiefs' offense was outstanding, as quarterback Patrick Mahomes threw for 360 yards and five touchdowns in a 44-21 rout against the Arizona Cardinals. Herbert will have to out-duel Mahomes Thursday night with Mike Williams and a handful of backups. Kansas City's defense didn't disappoint last weekend either, as the team held quarterback Kyler Murray and the Cardinals to seven points through three quarters. It's safe to say that Allen will be missed regardless of the result.
