Dec 29th 2018: Ross Millen has signed a new 18-month contract with Killie. The 24-year-old has been rewarded for his form over the past six months, which included the winning goal on his Premiership debut against then-league leaders Hearts at Tynecastle.

June 1st 2021: Ross Millen has left Kilmarnock following the expiration of his contract.
Manager Tommy Wright said: “We set Ross a deadline to get back to us about a contract extension, giving him time to think it over. The club didn’t get a response in time and we’ve now withdrawn our offer. It’s important that we have players here who want to play for the club. I want to thank Ross for his time at Killie, and wish him well.”
The full-back will depart after three years at the club having joined Killie in July 2018.
