O'Connor (lower body) will return for Friday's game against Tampa Bay, Evan Rawal of the Denver Gazette reports.
O'Connor had been trending toward a Friday return in recent days, and the Avalanche are set to activate him from long-term injured reserve ahead of their matchup against the Lightning. The 30-year-old recorded no goals, two assists, 11 hits, four PIM and three blocked shots while averaging 11:27 of ice time across 13 regular-season appearances with Colorado, and he's slated to take on a bottom-six role now that he's healthy.
