The midfielder has been at Leeds since the age of eleven, and is now set to feature for another Yorkshire club after moving to the New York Stadium.
There have been plenty of incomings at Elland Road this week, but the club were quick to recognise their former winger, who was released after his contract expired this summer.
The Millers secured their Championship place with just one fixture to spare last season, with manager Steve Evans famously donning a sombrero to celebrate in the club's final match, a 0-0 draw with Yorkshire rivals Leeds.
White, who had an ankle injury for much of the last 12 months, made his only outing of the campaign in that match, coming on for the final 19 minutes for his last ever Leeds appearance, and it is somewhat ironic that he has ended up joining the side that he was facing in his last game at the club - having featured in over 100 matches for the Whites in his 13 years at the Elland Road.
The club's decision to wish their former player luck may be rarely common these days, but considering great things were expected of the left-sided player as a youngster, and many supporters being disappointed with his eventual release, it is likely most will genuinely wish good fortune to the 23-year-old in his future.
