Tkachuk (upper body) will not dress for Thursday's game against the Sharks.

Tkachuk remains day-to-day, per Pat Steinberg of Sportsnet 960 The Fan, but coach Glen Gulutzan also indicated that he does not have a timeline for return. The star winger will likely be evaluated daily moving forward, with his next opportunity to rejoin the lineup arriving Sunday when the Flames travel to Las Vegas.
