Bruce, 34, has signed until the end of the season after Wigan Athletic agreed to terminate his contract.

The son of former Manchester United centre-half Steve, he has only played once for Wigan this season, an EFL Cup defeat by Rotherham in August.

"As soon as I left the Rangers game I thought, I wouldn't mind joining this group," Bruce said.

"I had a couple of opportunities in England too but I fancied a fresh challenge and it's one that I'm looking forward to.

"Everyone knows that Kilmarnock are having a great season and once I got everything finished with Wigan then I wanted to jump on the bandwagon and hopefully help the club be successful."

Bruce, who began his senior career with Blackburn Rovers, joined Wigan from Bury after a loan spell from Hull City.

But he has only played 13 times for the side promoted to the Championship last season since signing in summer 2017.
