Whether there is a fee involved remains to be seen but what we do know is that our most consistent player has now moved on.
That familiar feeling back again.
We've seen it so many times before but Leeds have let Warnock go at a crucial time of the season. While he may be 33 and wanting to secure his future (who wouldn't), Warnock was head and shoulders above the rest of our squad in terms of consistent performances.
The Derby deal seemed to come from nowhere but Warnock will now be pushing for promotion and the Premier League. The former Liverpool man made 22 appearances for the club this season, but he has now signed an 18-month deal with the Rams.
He also has the option of a further year, much more than Leeds owner Massimo Cellino was willing to give him. In his 67 games for Leeds, Warnock didn't do much wrong.
In fact he was criticised by some sections of the Leeds support and it is still baffling to see why. His tough tackling and calm head was vital for Leeds last season and this year he's saved the Whites on many occasions.
Now Leeds move on again with the first job to be find a new captain. Youngster Charlie Taylor looks like the man who will fill Warnock's boots for the remainder of the season.
New signings look unlikely with the Cellino's future in doubt. So Leeds must do it the hard way once again.
