Jon Gruden is ‘concerned’ about injuries to starting receivers Henry Ruggs, Bryan Edwards

It’s a new week and there are new injury worries for the Raiders, who have been dealing with a rash of injuries since Week 1. The latest big issue is at wide receiver, as coach Jon Gruden said Monday he is “concerned” about injuries to rookie starters Henry Ruggs III and Bryan Edwards.

Ruggs, a first-round pick, missed Sunday’s 36-20 loss at New England with a hamstring injury. Edwards suffered an ankle injury in the third quarter. Gruden said he will need to get more information from his medical team before knowing exactly how big of a deal the injuries are.

Nelson Agholor played for Ruggs and slot receiver Hunter Renfrow led the Raiders with six catches for 84 yards and a touchdown Sunday. Agholor, Renfrow and Zay Jones would all play bigger roles against visiting Buffalo on Sunday if Ruggs and Edwards, who became a starter when Tyrell Williams was lost for the season in August with a shoulder injury, can’t play.

Meanwhile, there is better news about right tackle Trent Brown (calf) and middle linebacker Nick Kwiatkoski (pec). Gruden said he is “hopeful” that both players will be able to play Sunday. They haven’t practiced or played since being hurt in Week 1.

Also, backup quarterback Marcus Mariota might begin the process of getting off of the injured reserve this week. That might not be the case with rookie linebacker Tanner Muse.
