"Hopefully it's not that serious, and we can get him back in the lineup here soon," Bednar said. "I guess it depends on what you classify as serious. Every game without him is not good, but hopefully he can get healthy and get back in and join us here soon."
MacKinnon left Tuesday's game in Vancouver with 6:04 left in the second period after he collided with the Canucks' Alexander Edler near the end boards. He went to the locker room to be evaluated and was later ruled out of returning to the contest.
"He's going to get reevaluated today, and we'll see how he is and go from there," Bednar said on the radio show. "The first indication is it is not real serious. He may miss a game or two or three, you just don't know how long it will be… It certainly could be worse."
MacKinnon recorded an assist and had a plus-2 rating prior to leaving Tuesday's contest, bringing his season point total to 61--second most in the league this year. The five-year veteran's 24 goals on the year already ties his career high, while his 37 assists are two shy of his personal best, both of which he set during his Calder Trophy-winning campaign as a rookie in 2013-14.
The 22-year-old represented the Avalanche at the NHL All-Star Game last weekend.
