St. Louis Blues forward Vladimir Tarasenko injured his right hand Saturday night against Nashville and will undergo surgery Wednesday.
The club said he will be reevaluated in six weeks, which would keep him out for the remainder of the regular season and the first two weeks of the playoffs.
The surgery will be performed Wednesday by Dr. Charles Goldfarb of Washington University Orthopedics and Barnes-Jewish Hospital.
It's another tough injury blow for the Blues, who recently welcomed back injured forward Vladimir Sobotka after a 12-game absence because of a leg injury. Leading goal scorer Alexander Steen missed 11 games earlier this season with a concussion.
The 22-year-old Tarasenko is sixth among Blues' scorers with 21 goals and 43 points. He scored his 21st goal Saturday night during the Blues' 4-1 victory at Nashville.
He also has a plus-minus rating of plus-20, which ranks 18th overall among NHL forwards
In 102 games with the Blues, the Russian forward has 29 goals and 62 points. He was one of two first-round picks by the Blues in 2010, drafted 16th overall and just two spots behind teammate Jaden Schwartz.
The Blues have recalled 20-year-old winger Dmitrij Jaskin from their Chicago Wolves farm club in the American Hockey League.
Jaskin has a goal and an assist in nine game with the Blues this season. He ranks third on the Wolves in scoring with 15 goals and 29 points in 42 games.
He was a second-round draft pick by the Blues in 2011 and like Tarasenko is also from Russia.
