Toronto FC star striker Sebastian Giovinco is listed as day-to-day with an adductor injury.
An MRI showed a Grade 1 strain, which is the mildest on the injury scale. Toronto coach Greg Vanney says the Italian is progressing quickly.
But TFC may not want to risk its marquee man in Wednesday's first leg of the Amway Canadian Championship semifinal against the visiting Montreal Impact. The second leg is June 8 in Montreal.
Giovinco, who left in the 22nd minute of Toronto's 3-0 road loss to the New York Bed Bulls on Saturday, did not train with the main squad in the portion of practice Tuesday that was open to the media.
Toronto's two other designated players are unavailable. Midfielder Michael Bradley is with the U.S. team at Copa America while striker Jozy Altidore (hamstring) is injured.
Midfielder Will Johnson is away with the Canadian team. Rookie forward Tsubasa Endoh is still making his way back from a leg injury.
On the plus side, French midfielder Benoit Cheyrou has recovered from a quad injury.
