Frankie McAvoy says he is optimistic about Matthew Olosunde's condition with the Preston North End defender to undergo a scan to learn the severity of his injury.
Olosunde made his much-anticipated Lilywhites debut during the defeat to Blackburn Rovers on Saturday, deputising at right wing-back in the wake of Tom Barkhuizen's absence.
In adverse weather conditions, the 23-year-old battled valiantly on the flank and enjoyed some success in the first-half as he looked to endeavour forward.
The summer signing from Rotherham United, who has spent the last five months out of action with an Achilles injury, was substituted in the 82nd minute with McAvoy citing a groin issue as the reason for his withdrawal.
"Matthew, for his first time (playing), I have no doubt he will do well for us," said McAvoy.
"Great energy, great athleticm and works up and down that line for us - we just need to get him to be a wee bit better on the ball at times.
"He did extremely well in the main I felt.
"We will get him scanned, he has overstretched and feels he has tweaked his groin a bit."
North End were without central defenders Sepp van den Berg and Andrew Hughes for the fixture against Blackburn as both Jordan Storey and Greg Cunningham were drafted into a makeshift defensive three.
Asked for an update on the condition of Hughes and Van den Berg, McAvoy replied: "We gave them every chance to be fit for the game and the physios have worked hard with them but they weren’t 100% today so we didn’t want to take any risks with them."
