Derby County striker Jack Marriott has undergone a groin procedure.
Marriott, 25, has not trained with the Rams’ squad since they returned to work end of May, following a break in the season owing to the COVID-19 outbreak.
Manager Phillip Cocu says Marriott could miss the remainder of the 2019/20 campaign after going under the knife.
Marriott has made 34 appearances in all competitions for Derby so far this season, scoring three times.
“I think almost everyone is fit,” Cocu told RamsTV ahead of Saturday’s away fixture at Millwall as Derby return to action after a three-month break, albeit behind closed doors.
“Jack has had small surgery and he will be out for, most likely, the rest of the season.
“We will see how he comes out of the surgery in the next couple of weeks.”
Marriott is joined on the sidelines by Polish midfielder Krystian Bielik, who will certainly miss the rest of the season.
Bielik sustained a long-term knee injury at the beginning of January but, otherwise, Cocu has a full-strength squad to pick from when the Rams head to The Den.
Cocu said: “We have a lot of options to choose from and that’s important with the games we have to play in the next few weeks.
“We will need everyone to be fit and in top form.”
