In an already disappointing season, the Raiders received another huge blow Friday.
The Raiders reportedly will be without running back Marshawn Lynch for at least one month with a groin injury.
NFL Media's Ian Rapoport was first to report the news.
Sources: #Raiders RB Marshawn Lynch is out at least a month because of a groin injury. Lynch had his MRI this week. Oakland is on a bye, but the bad news continues.— Ian Rapoport (@RapSheet) October 19, 2018
Lynch sustained the injury Sunday against the Seahawks in a 27-3 loss in London. He rushed for 45 yards on 13 carries.
The 32-year-old has rushed for 376 yards and three touchdowns this season on 4.2 yards per carry. He's averaging 62.7 yards per game, up three yards from last season.
With Lynch out, the Raiders must turn to running backs Doug Martin, Jalen Richard and DeAndre Washington. The 1-5 Raiders are on a bye this week and play the Colts in their next contest on Sunday, Oct. 28.
