Canadiens general manager Marc Bergevin announced the signings of two Swedish draft picks on Tuesday: defenceman Magnus Nygren and forward Sebastian Collberg.

The club also announced that defenceman Alexei Emelin underwent successful reconstructive surgery on the ACL and MCL in his left knee and that his recovery is estimated at six months. Emelin suffered the injury when he collided with the Boston Bruins’ Milan Lucic in the first period of a game on April 6 at the Bell Centre. The surgery was delayed to allow the swelling in Emelin’s knee to subside.

Nygren, 22, was signed to a two-year contract after playing 51 games with Karlstad Farjestad in the Swedish elite league. He led all defencemen with 13 goals and had 32 points, to go along with a plus-11 and 49 penalty minutes and won the Salming Trophy as the league’s top defenceman. The 6-foot-1, 191-pounder was selected by the Canadiens in the fourth round (113th overall) at the 2011 NHL entry draft.
