Matthews' status for Saturday's game against the Edmonton Oilers currently remains unclear.
The 23-year-old appeared to be in discomfort after going hard into the boards on Wednesday against the Calgary Flames.
Maple Leafs head coach Sheldon Keefe said postgame that Matthews has battled a wrist ailment all year.
"We don't think it's anything more at this point than what he's been dealing with virtually all season," Keefe said.
Matthews, who leads the NHL with 18 goals, is likely considered a front-runner for the Hart Trophy as the league's most valuable player.
