FC Halifax Town continue their FA Cup campaign when they host fellow National League North side Stalybridge at The Shay on Saturday (3pm).
Celtic have won only three of their 14 games in all competitions this season, conceding 31 goals in the process.
They have kept just one clean sheet and conceded three or more goals on six occasions.
Andy Owens is their top-scorer with six goals. He started his career in the youth ranks at Liverpool and has had a nomadic career playing for Stafford Rangers, Mansfield, Southport and Telford amongst others.
He has also played twice for the England C team.
Stalybridge have conceded the first goal in 10 of their matches this season, and have won just once in their eight away games this campaign.
Stalybridge beat Witton Albion 2-1 in their FA Cup replay after a draw in the first game.
Second-half goals by Matty Hughes and Andy Owens put Stalybridge 2-0 up before Thomas Owens got a goal back for Witton.
Town have already beaten Stalybridge 1-0 at The Shay this season, thanks to a penalty from Liam King.
Halifax beat Ashton Athletic 5-0 in the previous round thanks to goals from Tom Denton, Danny Hone, Jordan Sinnott, Alex Simmons and Richard Peniket.
Matty Kosylo is expected to be out for a further two weeks with a small tear in his cartilage.
The injury, which is not operable, has already kept the midfielder out of action for three weeks since his last appearance as a substitute in the 2-2 draw at Salford.
Matty Brown trained this week and came through a structured game unscathed.
But he won’t be involved on Saturday, with Heath saying it’s “far too early” for the centre-back.
Nathan Hotte should be available on Saturday following a groin injury, but defender Keil O’Brien has returned to Southport after his loan expired.
Alex Simmons missed training on Tuesday with a calf problem but it was hoped he would train on Thursday night.
If they keep a clean sheet on Saturday, it will be the first time Halifax will have kept three consecutive clean sheets since October 2014.
If Town win, it will be the first time they’ll have won three games in a row since August 2014.
