Roslovic (lower body) will be in action against the Avalanche on Tuesday, Lance Hornby of The Toronto Sun reports.
Roslovic is expected to jump into a first-line role for the Leafs on Tuesday, in part due to the absence of Colton Sissons (lower body), who was labeled week-to-week. For the 29-year-old Roslovic, he returns following just a one-game absence, having racked up 12 points in his last eight contests.
