Ann Arbor — Michigan’s hockey team was dealt a big blow with the loss of sophomore forward Will Lockwood, who will be sidelined at least a month and possibly the season due to an injury suffered in last week’s World Junior Championships.

Lockwood, who had shoulder surgery last summer, suffered an upper-body injury while playing for the U.S. team, which went on to win a bronze medal in Buffalo, N.Y.

Lockwood had four goals and 11 points in 16 games for the Wolverines this season while playing on the line of freshman Josh Norris and sophomore Jake Slaker.

“Last year he had a shoulder issue and had surgery last summer,” Michigan coach Mel Pearson said of Lockwood. “I’m not sure if it’s the same shoulder or not, but it’s an upper-body injury and he will have to have surgery, if not now then later. He won’t be able to play for a month and he could just have surgery now, get well and get ready for next season.

“It’s definitely a bummer for us and a bummer for him. We don’t have a lot of guys like Will, the speed and skill set that he has and he looked good in that last game (for U.S. team).”

Pearson said he has options to play with Norris and Slaker, including freshman Dakota Raabe and sophomore James Sanchez.

Michigan is 8-10-2 (3-7-2 Big Ten), but played well against top-ranked Notre Dame (18-3-1, 12-0-0) this past weekend, losing a pair of 2-1 games.

“We’re not far off the mark,” said Pearson, who is in his first year as head coach of the Wolverines. “You want to give yourself an opportunity to win and we did that, but couldn’t finish. We’re going to have to win 2-1 and 3-2 moving forward because that line (Cooper Marody, Tony Calderone, and Dexter Dancs) isn’t going to score every game.”

Marody leads the league in assists (17) and scoring (19) in Big Ten play, with Calderone leading the league in goals (12) in Big Ten games. Calderone already has matched his goals total (15) of a year ago, scoring his 15th overall in the loss Friday night at Yost Arena.

“I’m not surprised,” former Michigan head coach Red Berenson said of Calderone’s play. “Tony came here with high expectations, and I’m the first one to criticize him since his first year he couldn’t get out of his own way. He was a great kid, a great player, but scored just three goals and we had him on the power play, and now he’s finally become the player and that’s what college sports is about, you finally become the player that you wanted to become, that they thought you could become. The coaches have been wanting you to get there and when you finally get there it’s great.”

Michigan will play at Minnesota this weekend. Lockwood had an assist in a 5-4 overtime win over Minnesota Nov. 10, then had a goal and assist the following night in a 6-6 tie with the Gophers.
