"I was here working out with the guys, did one exercise that kind of [tweaked it]," Colborne said after Monday's practice at Family Sports Center. "It is not the way you want to go into camp, obviously. I had such a good summer of training and was really looking forward to coming in and getting off to a great start. That's the way it is. I've been working hard in the weight room to make sure that I get my cardio back and everything and be able to step in as soon as possible when the time comes."
Colborne began skating on his own last week and took part in a few drills during team practices on Friday and Saturday, albeit in a red, non-contact jersey. He was finally able to shed that bright sweater on Monday, donning a regular gray Avalanche practice jersey instead.
"It was fun," Colborne said of his first practice. "It has been a tough couple of weeks, but thanks to the medical staff and everyone for getting me back. I felt good out there. Everything felt as close to normal as possible, and it is a big step."
When and where Colborne will fit in the Avs' lineup this season isn't fully known yet, but head coach Jared Bednar seemed encouraged with what he saw from the center after his first team session.
"He's got to keep practicing," Bednar said. "We got to get him in some practices. Once he's done that long enough, we'll get him in some games."
Colborne was on the team's unofficial fifth line with Gabriel Bourque and Carl Soderberg during Monday's session.
