An ankle infection has landed forward Pavel Buchnevich on injured reserve, where he is expected to reside until after the All-Star break.

The Blues announced Tuesday that Buchnevich, who was a surprise no-show at practice Monday, has undergone a minor operation to address an infection to his ankle, where he suffered a contusion at some point earlier this season. He will be reevaluated after the All-Star break, which runs from Jan. 31-Feb. 10.

Buchnevich, 27, ranks second on the Blues with 15 goals, tied for third with 23 assists and third with 38 points this season.

"It's tough luck for him and us," coach Craig Berube said Tuesday. "He's an all-around guy. We've used him in every situation. He's a real good defensive player and penalty killer and offensive player, too. We'll miss him."

The Blues also had some good news Tuesday: defenseman Torey Krug and forward Vladimir Tarasenko have been activated from IR. Berube said both will play Tuesday night against the Buffalo Sabres.

Krug has been out with a lower-body injury since last playing Dec. 23. St. Louis' primary quarterback on the power play, Krug has 17 points (five goals, 12 assists) in 31 games this season.

Tarasenko (hand injury) hasn't played since New Year's Eve. He has tallied 29 points (10 goals, 19 assists), fifth on the team, in 34 games this season.

"It's good to have them back," Berube said. "Both are players that can provide different things -- offense, power play, scoring, puck movement, things like that. They're good players for us."

Also penciled in Tuesday is forward Logan Brown, who has been out since last playing Dec. 29. Brown has played in only nine games this season, registering two assists.

"He's got to stay healthy, first of all," Berube said. "He's been injured most of the season. If you go back to last year, I guess the last month or two, he had a pretty good impact on our team, playing. Pretty consistent hockey. Strong on pucks. He's got good offensive abilities, good hands and things like that. He's just got to get back to that."

The Blues conclude a seven-game homestand Tuesday night. Coverage begins at 6:30 p.m. on Bally Sports Midwest.
