Howard underwent an ultrasound on Monday, which revealed the tear. Howard had to be carted off the ice on Saturday after less than two minutes of play after his legs split awkwardly while he was trying to get back to the net on a wraparound goal attempt.
Earlier that day, he was named to the NHL All-Star team for the second time in his career. He will now miss the upcoming game on Jan. 25 due to the injury.
Howard, 30, is 16-7-7 with a 2.11 goals against average and .920 save percentage in 31 starts this season.
