It happened more than seven years ago, but Rotherham United new boy Kelvin Wilson clearly remembers the day things came to a head with Greg Halford.
The pair are now Millers teammates, yet back in 2009 friendship was the last thing on their minds as they did battle at Bramall Lane, with Wilson wearing the colours of Nottingham Forest and Halford playing for Sheffield United.
Centre-half Wilson lasted only 16 minutes of the April 13 Easter Monday 0-0 draw before he was sent off for headbutting his Blades opponent.
“It was just stupid,” the 30-year-old told The Star. “There were three games left in the season and Forest were in a relegation fight. “We had a free-kick - I was playing left-back, for some reason - and I tried to get the ball off him, but he wouldn’t give it me back.
“We needed to win the game and Greg had the ball under his arm. I was chasing him round in circles and lost my head for a minute.”
Indeed. And Halford almost lost his for longer.
Wilson is quick to point out the pair, who later played together at Forest, are pals today. “Me and Greg are fine,” he grinned.
Forest stayed up but Wilson’s red card meant he didn’t play again that season.
The former Celtic defender arrived at AESSEAL New York Stadium earlier this week on a one-year deal, having put injury problems at Forest over the last three years behind him, but will sit out tomorrow’s opening-day showdown at home to Wolves as he builds up his fitness.
Millers manager Alan Stubbs reckons the defender could be ready for action inside a fortnight.
Wilson said: “This is the fittest I have felt for a long time. It’s football, anything can occur, but I am fit and I have been doing bits with Warney (fitness coach Paul Warne). When the gaffer feels that I am fit enough to be involved is up to the gaffer.”
Halford, now entering his second season with Rotherham, is often the target of banter from other members of the first-team squad.
“Like I say, we are fine,” Wilson added with a mischievous smile. “But a few of the lads shook my hand when I came in!”
