Safety Brandon Meriweather will miss at least Sunday’s game against Atlanta because his pregame collision with receiver Aldrick Robinson on Sunday exacerbated the MCL and PCL injuries in his left knee, coach Mike Shanahan said Monday afternoon.

“I think we’ll be able to tell in a week’s time exactly the length it will be, but right now he will be out for the next game,” Shanahan said.


Meriweather would have been active for Sunday’s 24-22 victory over Tampa Bay if it weren’t for the collision, Shanahan said. It would have been his regular-season Redskins debut. He sprained knee ligaments in practice on Sept. 3 after initially injuring his knee in a preseason game against Chicago on Aug. 18.

He and Robinson never saw each other as Meriweather ran after a thrown ball and Robinson loosened up in the end zone.

Video of the incident shows the two collided head-to-head. Meriweather fell awkwardly with his weight over his bent left leg. Robinson was unconscious before he hit the ground.

“He was knocked out for over a minute,” Shanahan said. “So any time you’re knocked out for that length of time, you go through a procedure according to the NFL. He’s been with the doctors today, and he feels very good right now. It looks good, but he’s going to have to take some tests over the next couple days. And if he looks OK and he passes those tests, he’ll be able to practice and potentially play. If not, then he’ll have to wait until his signs are correct.”

Robinson has 104 receiving yards on seven catches through three games.

Reed Doughty started in place of Meriweather and had six tackles. DeJon Gomes started the first three games in Meriweather’s place, but the Redskins went with Doughty because Meriweather took most of the practice repetitions last week. Coaches believed Doughty, a seven-year veteran, would be more reliable considering the lack of practice time, Shanahan said.
