Defensive tackle Aaron Donald may have felt good in his return to game action on Sunday, but he was far from satisfied with his performance in the Rams' 27-20 loss to the Redskins.

"It definitely felt good being back on the field playing football," Donald said postgame, "but I didn't play too good."

"I didn't win my one-on-ones," he added. "When I have one-on-ones I usually win those, just doing too much thinking. And you can try to say that [it was because] I didn't play. But that's on me — I need to play better."

Head coach Sean McVay, however, did not appear worried with the fourth-year pro's showing against Washington. Donald returned to the team just a week before Sunday's kickoff, after choosing to remain away while his representation negotiated a contract extension with the club. He participated in just three full practices before taking the field in game action.

McVay said all circumstances considered, Donald showcased flashes of what makes him one of the best defensive players in the league — including a tackle for loss and a quarterback hit in the second half — but will continue to get more comfortable as he finds his rhythm on field.

"That's the first time he's had live action in a year or so," McVay said Monday. "I thought he did some good things as the game progressed, made some plays, effected some of the schemes that they were running. You could see his get off and some of those things that make Aaron rare did show up. I think we'll see him get more and more comfortable as the season progresses."

But Donald won't have much time this week to prepare for his next game as the Rams will head to San Francisco for a Thursday night football game in Week 3. McVay and Donald did not seem concerned by the quick turnaround. 

"He came out of the game and he felt good today when he talked with Director of Sports Performance Reggie Scott and strength coach Ted Rath," McVay said. "With him feeling good we're on a good track for him to be ready to go on Thursday."

"I'll be good, I'm gonna be ready, a lot more ready than I was this week," Donald said.
