Kilgallon, now 31, came up through the Leeds United youth academy, and made his debut all the way back in 2002 having impressed in the Elland Road ranks.
Kilgallon ended up playing 95 games for Leeds, becoming yet another success story of the Leeds United academy alongside Aaron Lennon, Scott Carson and James Milner.
However, his success at Elland Road eventually led to a 2007 move to Yorkshire rivals Sheffield United, and his career has since taken him to Sunderland and now Blackburn Rovers, with loan spells at Middlesbrough and Doncaster Rovers sandwiched in between.
Kilgallon is currently a regular for Gary Bowyer's Rovers side, and made his first return to Elland Road since leaving in 2007 on Saturday afternoon.
That game ended in a 3-0 win for Blackburn, and Kilgallon spoke after the game about his return to West Yorkshire - and made a shock revelation.
Kilgallon said that he didn't really want to leave Leeds just over eight years ago, and as Eurosport reported, he added that Dennis Wise had a big part to play in it.
"When I left I never really wanted to go, but Dennis Wise came in, there was a big change around and I was gone." he said. "But I had some great years here and this is the first time I've been back to play here and it's nice."
At 31, it seems unlikely that Kilgallon will make a return to Leeds as a player, but it's clear that he still thinks fondly of the club that gave him his first chance in football.
