Brown (groin) has been ruled out for Sunday's game against the Bills.

Analysis:

A calf injury ended Brown's tenure in San Diego, and he's been plagued by hamstring and groin issues since joining Oakland. He'll miss Sunday's game and his inability to practice in any capacity during the week suggests he may very well have played his final snap of the season. Brown is still sitting with just three career touchdowns, with only one since 2011.
