Andrew Shaw undergoes knee surgery, out six months

The Montreal Canadiens announced that Andrew Shaw will be out for a minimum of six months following surgery on his left knee earlier today.

Shaw has been sidelined since March 13, following a collision with former Canadien Greg Pateryn in a game against the Dallas Stars. Following the hit, he was diagnosed with a concussion as well as a knee injury. Shaw agreed to proceed with surgery on his knee once he had recovered from the concussion.

Despite the obvious head contact in the play, you do see some knee on knee contact, which may have resulted in this injury.

Shaw is the second Canadien to undergo an off-season surgery which could jeopardize the start of their season. Paul Byron underwent shoulder surgery earlier this month. Shea Weber had surgery recently as well.

The 26 year old recorded ten goals and ten assists, as well as 53 penalty minutes in his second year with the Habs. Shaw is currently in the second year of a six-year contract with the club, and injury luck hasn't been to kind to him recently.
