The Rangers say Sunday night that the 28-year-old left winger has a torn anterior cruciate ligament, a second degree sprain of the medial collateral ligament and a medial meniscus tear in his right knee that will require season-ending surgery. An MRI revealed the damage that occurred in the third period New York's 2-1 win at St. Louis on Saturday night.
Frolov, injured when Blues forward Brad Winchester fell over his leg, signed a one-year, $3 million deal with the Rangers after spending seven seasons with the Los Angeles Kings. He posted seven goals and nine assists in New York's first 43 games after scoring 19 goals last season.
The Rangers recalled forward Kris Newbury from the Connecticut Whale of the American Hockey League.
