ST. LOUIS -- Concussions continue to take their toll on the St. Louis Blues.
David Perron to Andy McDonald to Carlo Colaiacovo all have dealt with head injuries in the past year and have made recoveries. McDonald, though, is in the process of dealing with yet another concussion.
Alex Steen's name may be added to the list.
Steen will not play Friday night when the Blues (21-11-4) host the Nashville Predators (19-14-1) because of what coach Ken Hitchcock called "concussion-like symptoms" believed to have been suffered Monday when the Blues hosted Dallas.
Steen, who is tied for the team lead in points (with David Backes) with 24, played Tuesday in Detroit and skated Thursday at practice, but Hitchcock said Steen didn't feel right and the team is holding him out Friday and likely Saturday night in Detroit before giving a further update.
"Looks like in the Dallas game, there was a hit in the Dallas game," Hitchcock said. "He didn't feel right after practice yesterday. We'll just hold him out ... it's day to day or what it is. Right now, he can't play today."
It would be the first concussion suffered in Steen's career if he has one.
"We'll let you know in a couple days on Steener how things are going there," Hitchcock said. "... We'll give you an update in a day or two.
"We're erring on the side of caution and we'll see in a day or two. It might be nothing and away we go, but you want to be safe."
While the Blues will suddenly be subtracting Steen from the lineup, they will be adding T.J. Oshie (wrist), Jamie Langenbrunner (flu) and Vladimir Sobotka (ankle) back into the lineup Friday night.
All three skated Friday morning and were deemed fit to go by Hitchcock, although Langenbrunner was declared fit Thursday after missing two games.
Oshie also missed two games after injuring his left wrist a week ago in Phoenix, while Sobotka has missed seven games after taking a puck off his ankle during a practice Dec. 12.
"Both guys are in, good to go," Hitchcock said of Oshie and Sobotka. "Both feel good enough to play. Both guys felt a lot better today after yesterday's practice. That's a good sign.
"Lags is back to normal. Three guys in and one guy down, so that's good."
Although Hitchcock was unsure of Friday night's lineup, it's likely that Adam Cracknell will be the one that goes to the press box as a healthy scratch.
Cracknell was recalled in time for Monday's game against Dallas.
"With those three guys in, that adds to our roster up front for sure," Hitchcock said. "We'll have to get somebody to replace Steen on that big line. I'm not 100 percent sure which way we're going to go yet.
