Check out the latest NFL news and rumors below. 

• The game wasn't the only thing the Chargers lost. Star wide receiver Keenan Allen left the game with a knee injury that Ian Rapoport of reports the Chargers suspect is an ACL tear.

• Rapoport reported Sunday morning that Larry Fitzgerald expects to retire after the 2016 season. However, that report was contradicted by one on Monday from ESPN's Adam Schefter, who says Fitzgerald has no plans to retire

• Russell Wilson's sprained ankle is "significant" and could keep the Seattle Seahawks quarterback out of Week 2, Rapoport reports. He also expects the Seahawks to add a veteran quarterback. 

• The New Orleans Saints lost to the Oakland Raiders and lost No. 1 cornerback Delvin Breaux in the process. Rapoport reports that Breaux broke his fibula.
