New signing Koki Mizuno left Airdrie on crutches today after injuring his ankle in the 5-0 win over Gretna.
The midfielder over stretched for a ball on the half-way line after 35 minutes and after a couple of minutes of treatment was replaced by Nicky Riley.
Celtic were already leading 4-0 at that point with Mizuno playing a part in the first goal for Derek Riordan and the fourth from Kevin Cawley.
Riordan also scored in the 14th minute with Mark Millar also on target in the first half before Chris Killen completed the scoring in the second half.
Joe Doumbe and Mark Wilson also featured with Wilson getting a good run out at left back in the second half although barely tested defensively.
