NFL Media Insider Ian Rapoport reports that Chargers wideout Keenan Allen has a lacerated kidney, per two sources.

The Chargers have ended his season, placing him on IR.

It's a huge blow to the offense that was struggling to run the ball this season behind rookie Melvin Gordon. A lot was falling on QB Philip Rivers' shoulders, and it's likely to stay that way despite not having his top target the rest of the year. Stevie Johnson and Malcom Floyd will see increased work at receiver, but the team could now really turn to TEs Antonio Gates and Ladarius Green, with RB Danny Woodhead likely continuing to be a key part of the passing game as well. Dontrelle Inman and Jacoby Jones are next up on the depth chart at WR. Inman will play much more than Jones.

The Chargers will be without Keenan Allen for "some time," coach Mike McCoy announced Monday.

Allen suffered a kidney injury Sunday when he landed hard at the end of a 13-yard touchdown catch in a 29-26 loss to the Ravens. The wide receiver traveled back from Baltimore to San Diego after the game with the team, but his symptoms worsened as the night progressed. He was checked into a San Diego hospital.

Obviously a huge blow to this offense and to QB Philip Rivers. Stevie Johnson, Malcom Floyd, Dontrelle Inman and Jacoby Jones will have to pick up the slack at WR. The team could also turn to TEs Antonio Gates and Ladarius Green, when healthy. Danny Woodhead should continue to be a force in the passing game from the RB position.

The most significant injury was to leading receiver Keenan Allen, who appeared to reinjure a hip flexor at the end of the first half on a 13-yard touchdown catch and did not return. The Chargers announced that Allen was suffering from muscle spasms.

Another report speculated it was a shoulder. But the team announced it was the back spasms that kept out Allen. With his Week 9 status up in the air, keep in mind the team has a Week 10 bye.

San Diego Chargers wide receiver Keenan Allen suffered a hip flexor injury Sunday that will be tested on Monday, a source told ESPN's Adam Schefter.

He finished Sunday's 27-20 loss against the Green Bay Packers with 14 receptions for 157 yards but missed the entire fourth quarter with the hip injury. He had 11 catches for 128 yards in the first half alone.

Allen said Sunday his hip "kept pulling me," according to the San Diego Union-Tribune. "I couldn't really run like I wanted to."

Allen does not believe the injury to be serious, the source said in the story. We can't always trust what a player says regarding an injury and his status for Week 7 is in question at least the way things stand right now.

The San Diego Chargers were on the brink of handing the Green Bay Packers their first regular season loss at Lambeau Field since December of 2013, but Keenan Allen, well on the way to a new franchise record for receptions, was lost to a hip injury and he took much of the team's momentum with him.

Allen was in the middle of an incredible performance at the time of his injury. The third-year wide receiver had already reached 14 catches and 157 yards midway through the third quarter, and his team had fought back from a 17-3 deficit to tie the game.

But on his 14th catch, he was slow to get up. He pointed at his hip when a trainer checked on him, and walked under his own power into the locker room for evaluation. Allen returned to the game shortly after, but eventually was ruled out for the remainder of the game with what the team characterized as a hip injury. The Chargers are home against Oakland in Week 7 in a late afternoon game.
