The Canadiens announced Tuesday that Mitchell would miss about two weeks with a right arm injury, Renaud Lavoie of TVA Sports reports. Mitchell will be evaluated by doctors in Montreal later this week to receive more definitive word on his injury, but it looks like his next game won't come until at least April. The bottom-six forward, who was acquired from the Sabres prior to the trade deadline, was held without a point in his first six games with the Canadiens.
