Brandon LaFell’s season is over, and now the Raiders need another wide receiver.

Because of course they do.

LaFell tore an Achilles tendon during Sunday’s 23-21 win over the Arizona Cardinals, a team source told NBC Sports California’s Scott Bair, but an MRI is needed to confirm that diagnosis.

LaFell was seen in the Raiders’ locker room at Arizona’s State Farm Stadium in a walking boot.

Even before LaFell’s season-ending injury, the Raiders were digging deep for receivers during this lost season. Marcell Ateman and Saeed Blacknall both made their NFL debuts Sunday, and although they both performed well, the Raiders will need depth at the position, especially if Martavis Bryant and Jordy Nelson can’t play because of their knee injuries. Both veterans missed the game in Arizona.

So, who’s available in Week 11 of an NFL season? The Raiders will have to find out.

Then again, Ateman ended up leading the Raiders with four catches for 50 yards -- including a big grab on their game-winning drive -- so maybe they’ll want to see what they have in him and Blacknall.
