Brandon LaFell

Brandon 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.

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.
