A specific timeline for his return has not been set, but Horvat could miss up to six weeks.
According to The Province, Horvat underwent an MRI on his right leg on Wednesday after appearing to injure it in the third period against the Carolina Hurricanes on Tuesday.
Horvat, 22, has 10 goals and 20 points in 28 games so far this season, good for second on the team in both categories.
Also on Thursday, the Canucks announced that they have recalled forward Michael Chaput and goaltender Thatcher Demko from their AHL team, the Utica Comets.
Chaput, 25, is the Comets’ third-highest scorer with eight goals and 15 points in 20 AHL games. He suited up for 68 games with the Canucks last season, registering four goals and nine points.
Demko was first called up last month but has yet to make his NHL debut. Now in his second year of pro hockey with Utica, the 21-year-old is one of the league’s most promising goalie prospects. In 15 games so far this season, he has a 2.50 goals against average and a .920 save percentage.
