The rear guard last played a competitive game on May 11, 2018 with the Sault Ste. Marie Greyhounds in the Ontario Hockey League Finals against the Hamilton Bulldogs. Timmins spent the following summer and the 2018-19 season recovering from the injury before he took meaningful steps this offseason to help him prepare for the upcoming campaign.
He participated in Colorado's development camp in late June and was also able to play in the 3-on-3 prospect scrimmage that concluded the on-ice portion of the camp. After a few more months of training, he joined the Avalanche rookies and skated against his peers from other organizations at the Anaheim Rookie Faceoff in early September.
Finally, he competed in three exhibition contests during this preseason and proved to club management and coaches with his play that he deserves to start the year with the NHL squad.
"To be honest, he's earned it. He had a tremendous preseason. Going into the summer, I would be lying if we didn't say that he was going to start in the AHL," said Avs executive vice president/general manager Joe Sakic. "The preseason that he had, he's [on the] opening day roster and he's going to play a lot of minutes, and we'll see where it goes.
"I give him a lot of credit. A year and a half without playing and what he did in the summer to get healthy and get to this next level and work real hard. You can just see it when he has the puck, his hockey sense, his IQ, he's done everything to earn his spot in the lineup."
Timmins played in both of the Avs preseason contests against the Vegas Golden Knights, and he scored in Colorado's exhibition game at the Minnesota Wild on Sept. 21. The St. Catharines, Ontario, native finished the preseason with one goal and 10 shots on net.
