Werenski (lower body) didn't practice Thursday, raising doubts regarding his availability against Colorado on Friday, Aaron Portzline of The Athletic reports.
Werenski was reportedly hurt after blocking a shot against Detroit on Tuesday, per Brian Hedger of The Columbus Dispatch. Offensively, Werenski has been rolling of late with one goal and eight assists, including two power-play points, in his last 10 outings. Unless Adam Boqvist (upper body) is cleared to play, the Jackets will need to bring up a defenseman from AHL Cleveland if Werenski can't go against the Avalanche.
