Los Angeles Chargers star wide receiver Keenan Allen appeared to be in line to return from a two-game absence this week, but he may have suffered a setback.
Jeff Miller of the Los Angeles Times reported that Allen left Thursday's practice early with a trainer. The 30-year-old has been dealing with a hamstring injury.
Allen suffered the injury in Los Angeles' Week 1 win over the Las Vegas Raiders. He recorded four catches for 66 yards before exiting the game.
While Allen has been sidelined, the Chargers have lost back-to-back games. The team's offense particularly struggled this past Sunday in a 38-10 loss to the Jacksonville Jaguars. Los Angeles quarterback Justin Herbert completed 25 of 45 passes for 297 yards, a touchdown and an interception.
Allen has managed to stay healthy in recent years, playing 16 games in four of the last five seasons. A five-time Pro Bowl selection, he is the most reliable target in the Chargers passing attack. If Allen misses more time, it will be detrimental to a Los Angeles team that is already reeling from injuries.
Herbert is playing through fractured rib cartilage. Star edge-rusher Joey Bosa was placed on injured reserve Wednesday after suffering a groin tear against the Jaguars that requires surgery. Pro Bowl offensive tackle Rashawn Slater tore his biceps and is likely to miss the remainder of the season. Cornerback J.C. Jackson (ankle) and center Corey Linsley (knee) are considered questionable after missing the game against Jacksonville.
The Chargers are looking to bounce back Sunday when they take on the Houston Texans.
