Report: Kidney injury ends season for Chargers' Allen

San Diego Chargers wide receiver Keenan Allen has a lacerated kidney that will sideline him for the remainder of the season.

The Chargers placed Allen, running back Branden Oliver (toe) and linebacker Tourek Williams (foot) on injured reserve Tuesday. The team also elevated wide receiver Javontee Herndon and cornerback Greg Ducre from the practice squad and re-signed cetner J.D. Walton.

Allen was injured before halftime of the Chargers' loss on Sunday to the Baltimore Ravens. He did not return for the second half and was taken to a San Diego hospital afterward.

Coach Mike McCoy said Monday that Allen would be out with a kidney injury, but media reports a day later indicated that the issue was significant and a medical procedure was done to stop the bleeding. He is expected to be recovered before next season.

Allen is second in the NFL this season in receptions with 67 and his 725 receiving yards rank third in the league. His catches were the third most in NFL history after eight weeks of the season. Only Julio Jones this year and Marvin Harrison have caught more passes at this point in the season.

With Allen out, the Chargers will turn to wide receiver Malcom Floyd, tight end Antonio Gates and running back Danny Woodhead as their primary receiving targets. Also in the receiver rotation are Stevie Johnson and Dontrelle Inman.

The Chargers (2-6) face the Chicago Bears (2-5) on Monday night.
