Wrexham captain Dean Keates is to have a toe operation which will see him miss the opening three weeks of the season.
Player-manager Andy Morrell confirmed the midfielder will have surgery on Friday and that he will be out of action for six weeks.
The injury hampered the 35-year-old during the closing stages of last season.
"He had it done on his other foot a couple of summers ago so we've got to do it," Morrell said.
"If we get it done now then we can have two and a half weeks out in pre-season and not miss six weeks of the season.
"He'll go in Friday and get that done. It's a big hit for us."
Keates, who captained Wrexham in their FA Trophy Final win over Grimsby, signed a new one-year contract with the club in May.
Morrell, whose side won 2-1 at Colwyn Bay in a friendly on Tuesday, is still hoping to sign Cameroon-born central defender Junior N'Tame.
N'Tame has recently been on trial at Wrexham and Morrell said the player was keen to join the club on a permanent basis.
"I've spoken with Don [Bircham, Wrexham chief executive] seeing what we've got and what we can afford," Morrell said.
"We'll go back to Junior and see. I think he's desperate to come and sign for us.
"There's a lot of things to work out for him but we'll speak to him over the next couple of days and see if there's anything in it."
