It was The Whites fifth consecutive defeat and it has shortened the odds on Reid's departure from Elland Road with William Hill revealing that they plan to open a book on his successor at Leeds.
"It looks bleak for Reid, we're already planning to open a book on his successor, with Paul Hart likely to be favourite," said Hill's spokesman Graham Sharpe.
Hills make Reid 1/8 to be out of his job at Leeds by the end of the season and 9/2 to survive.
And they have slashed Leeds to 8/15 to be relegated and 3/1 to finish bottom of the Premiership.
