Jim Goodwin admits losing Ryan Flynn to injury is a “bitter blow” ahead of the Paisley club's Scottish Cup fourth-round clash with Inverness Caley Thistle.
The experienced St Mirren midfielder replaced Jon Obika in the starting XI on Saturday after Jon Obika was ruled out with a groin strain.
Flynn was a big part of a strong first-half performance from the Buddies in Lanarkshire until he was forced off just before the break after overstretching his hamstring.
And Goodwin revealed he is set for a spell on the sidelines which could rule him out of the next two rounds of the competition, should the Saints defeat Inverness and progress into the quarter-finals.
Goodwin said: “Flynny has been out of the team for a long time and sometimes that happens. The body isn’t used to that intensity.
“He’s overstretched for a ball and his hamstring has gone. So that will be two to three weeks.
“I thought he was having a really good game as well.
"It’s a bitter blow for Ryan after waiting so patiently to get into the team.”
