The former Boyzone star is currently touring the UK but he was dealt a set back as he was making preparations to take to the stage at the Liverpool Echo Arena.
Keating hurt his ankle during a morning jog and has been left with a nasty limp.
In a post on his Twitter page, he writes: "Can't wait for Liverpool Echo Arena gig tonight. Almost broke my ankle running this morning. Hobbling around like a right egit now."
