The Leeds captain took to social media after his side's 1-0 loss to Fulham.
The defeat was boss Neil Redfearn's first home reverse of the season and Warnock, stand-in captain for Jason Pearce, was unimpressed with both the scoreline and his side's display.
However, the Leeds full-back did allay any injury fears supporters may have harboured after the 33-year-old had come off late in the game.
Warnock confirmed he left the field of play due to dehydration and cramp - not the suspected hamstring injury that was speculated about beforehand.
Poor result and poor performance today. Not pulled my hamstring I wasn't feeling well during the game and got dehydrated and cramped up.— Stephen Warnock (@StephenWarnock3) December 13, 2014
Boss Redfearn had earlier told reporters: “It’s his hamstring and might be a bit of tiredness as well. It is something we will assess on Monday.”
His press conference came before Warnock's Twitter update, however, meaning Leeds fans at least have one less thing to worry about.
Their side's position in the Championship table (19th) is another matter, though.
