Pisa Tinoisamoa back at practice

LAKE FOREST, Ill. -- Chicago Bears linebacker Pisa Tinoisamoa returned to practice Friday after sitting out on Thursday.

Tinoisamoa participated in the special teams portion of practice that was open to the media. The veteran underwent a knee scope Dec. 3, but was able to play in the final two games of the regular season.

"[The knee] probably [is] as good as it's going to feel," Tinoisamoa said. "It's not perfect, but I don't think anybody is feeling perfect right now. That's OK with me. When you get caught up in emotion and other stuff, there is no time to feel that injury. It's time to go out, have fun and let loose."

Sunday will mark Tinoisamoa's first postseason game since 2004, when he was with the St. Louis Rams.

"I feel like one of the rookies, it's been so long," Tinoisamoa said. "But it feels good to actually get back to a position where you can win the whole thing. I always believed I'd get back. Even when I was in St. Louis and the team was going through tough times, I was always optimistic. I thought we were going to the playoffs every year until we were mathematically eliminated. That's what kept me coming back. And when I came to Chicago [in 2009], I knew there was a real chance we'd be playoff contenders. That was one of reasons I signed here as opposed to Buffalo. I'm just so excited to be back in this position.

"I'll probably feel a lot of emotions on Sunday just because it's been so long. This is what you work for, and because I'm playing a significant role on this team, I'm going to be pumped up and ready to roll."

Fellow strongside linebacker Nick Roach practiced all week without restrictions despite separating his left shoulder on the first play of the Bears' 10-3 loss to the Green Bay Packers in the regular-season finale.

Meanwhile, defensive tackle Anthony Adams had his left calf wrapped but had full participation after being limited on Thursday.

The Bears released their injury report Friday afternoon, and no Chicago player was listed.
