ST. LOUIS -- T.J. Oshie was optimistic Thursday morning and it turned out to be well-founded. The St. Louis Blues activated him off injured reserve later in the day and announced he'll be in the lineup against the Nashville Predators.

Oshie, who sustained a concussion Oct. 28 against the Dallas Stars, skated again Thursday prior to the Blues facing the Predators. Oshie, who has one assist in eight games and has missed the past seven, skated for a fifth straight day without any setbacks and said in the morning he felt physically fit.

"I think so," Oshie said. "I've skated the last five, six days in a row now. I feel good out there. I've been riding the bike in here, I've been getting my workouts in.

"Whenever I do go it's probably going to take me a couple shifts. It's usually a period to kind of get your lungs going and get everything back in. I'm as ready as I will be."

Oshie needed medical clearance from team doctors before being activated from injured reserve and placed on the active roster.

"They need me to be 100-percent healthy," Oshie said of the doctors. "If I feel like I'm 100-percent healthy I'll try to be in there [Thursday].

"We're on the same page. That was a miserable first week that I had. If there's any chance that I'm at a higher risk of re-injuring my head or another concussion, I won't come back. But if I feel 100-percent ready and they feel 100 percent that I'm going to come back and not be at any higher risk than any other player, then I'll be back in."

Hitchcock was playing the cautious role earlier Thursday.

"He's been good for about three or four days but we haven't gotten approval from the medical people," Hitchcock said. "Until we get that, not playing. If we get a call in an hour or two hours or three hours after he has conversations with everybody connected, it's kind of out of our hands. If he gets a call, we'll put him in. If not, then we'll just keep going until somebody tells us. It's got to come from the doctors and the medical people before there's approval."

Oshie's return will come where he started the season, with a pair of familiar faces.

"With [David] Backes, right where they were before," Hitchcock said. "Backes and [Patrik] Berglund, the way we were the first two or three games at the start of the year, back to where we started the season, and let's just go from there."

The Predators (10-3-2, 22 points), who defeated the Blues (10-4-1, 21 points) 2-1 on Saturday at Scottrade Center on a third-period goal by James Neal, did not have a full team skate Thursday; only backup goalie Carter Hutton and defenseman Victor Bartley skated. It's become a routine for the Predators in recent games to not skate with a full team or at all on game days. The Predators did not skate at all here this past Saturday.
