The Seahawks clinched a playoff berth with Sunday's win at Washington, and they could be adding some weapons to their offense when they face the Rams this weekend with a chance to clinch the NFC West.

In addition to adding receiver Josh Gordon back to the roster this week, the Seahawks also will likely get back tight end Greg Olsen, who returned to practice last week from a foot injury that landed him on injured reserve last month.

"Greg Olson is returning this week," Seahawks coach Pete Carroll said. "He had a really good week last week, so he'll be back and ready to go, so if he makes it through the week and all that, we'll have a guy to add to it, so we've been really excited about whatever Greg contributes."

The Seahawks also got good injury news on a couple of potentially scary looking situations in Sunday's game. DK Metcalf, who landed awkwardly while trying to catch a pass in the back of the end zone, stayed in the game after what looked like a potential injury, and a day later he's doing OK, Carroll said.

"He is doing OK, remarkably," Carroll said. "I don't know how he made it out of that, but the extraordinary flexibility he needed just to get through that without injuring—it's a little bit better than my flexibility, so I really appreciate the fact he could pull that off."

Running back DeeJay Dallas, meanwhile, has an ankle sprain that will sideline him for a few weeks, but that's very good news considering he was carted off the field with an air cast on his lower leg, usually a sign of a very serious injury.

"He has a similar ankle sprain to what L.J. Collier had (last year), but not nearly as severe," Carroll said. "It's in the same kind of place and all that, but our guys are really hopeful that it's a few weeks."

Carroll said right tackle Brandon Shell "is going to try" to get back this week after missing Sunday's game with an ankle injury, but added they feel good about the way Cedric Ogbuehi played in Shell's place should they need to go to him again.

"Cedric's ready to go," Carroll said. "It was much cleaner than his first game. He did some good things in the first game, but this game he was poised, and the composure really showed up… I was really fired up about it."

Earlier in the day, Carroll said on 710 ESPN Seattle that left guard Mike Iupati is dealing with a stinger, which is an injury he has dealt with in the past. Jordan Simmons finished the game for Iupati, and Carroll did not have a timetable for Iupati getting back.
