Sundin sat out Saturday against the Buffalo Sabres after straining his groin last week. He is day-to-day.
Toronto plays at Buffalo on Friday and Ottawa on Saturday.
"I'm hoping for the weekend -- we'll see how it goes," Sundin said.
Antropov played less than three minutes against Buffalo on Saturday before leaving in the first period with a knee injury. No timetable has been set for his return.
Sundin leads the Leafs with 77 points (32-45) in 72 games and Antropov is second in team scoring with 52 points (26-56) in 70 games.
