These three Chargers ball-catchers will be asked to do much, much more without Keenan Allen around. Evan Habeeb USA TODAY Sports

Keenan Allen won't return for the final eight weeks with a lacerated kidney.

The Chargers star must be in pain -- just like his offense's chances without their No. 1 wideout.

There's simply no replacing a player who's second in the league in receptions (67) and third in receiving yards (725). But here are three Chargers who'll be asked to play their part for the rest of 2015:

1. Jacoby Jones, kick returner: The Bolts added Jones for his return ability, but loved his big-play skill set as a wide receiver. He's shown neither trait halfway through the 2015 season. Any contribution would help from a player who has yet to record his first catch as a Charger.

2. Dontrelle Inman, wide receiver: The relative unknown had a big two-game stretch for the Chargers late last year (12 receptions, 158 yards over two games). He'll be asked to stretch that production through eight games now. He'll provide Philip Rivers with a similar, big-bodied target.

3. Danny Woodhead, running back: Allen wasn't just a downfield threat; he was a security blanket for Rivers who's picked up the third-most first downs in football. It means a check-down target like Woodhead will see more of those crucial targets going forward. He'll be up for more work.
