Kyle Storer was sent to hospital after fracturing his cheekbone in Kidderminster's 0-0 FA Cup fourth qualifying round draw with Corby.
The former Nuneaton midfielder was forced to play the closing stages of the game with the injury.
"Kyle has fractured his cheekbone and fair play to the lad for wanting to carry on there," boss Steve Burr told BBC Hereford & Worcester.
"We had made the substitutions and he carried on for the last 15 minutes."
Clear goalscoring opportunities were at a premium in the tie although Corby were always lively going forward through their striking duo of Nick Rogan and Matt Rhead.
But the home side also posed a threat when Nick Wright's cross shot flew across the face of Corby keeper Chris Mackenzie's goal.
Storer then tested Mackenzie with a fierce drive following a corner, but the veteran keeper was equal to it as he tipped it around a post.
The Harriers boss, who had been to watch Corby twice prior to the tie, added: "We have got another bite at it but it was always going to be a tough game today.
"I think we made it hard for ourselves but I expected the game to be quite close.
"The only good thing to come out of today is that we have got another chance on Wednesday to progress in the tie."
Burr admits the growing injury list is a concern as, in addition to the likely long-term loss of Kyle Storer, full back Lee Vaughan is also a major doubt for the replay.
"If it is a broken cheekbone then Kyle is likely to be out for six to eight weeks," he said.
"But we will have to wait and see what the doctor says when he comes back.
"As for Lee, he got a really nasty dead leg so he could well be struggling."
