Adam Pearson has left Leeds United.
Chief executive Adam Pearson has left Leeds United, report BBC Radio Leeds.
Pearson joined the club in the summer and was seen as a key asset in their improved off-field stability.
The reasons cited are personal, with BBC Radio Leeds's Adam Pope telling the station he believed there was 'nothing sinister' behind his departure.
He told the station: "I've made contact. It appears doing the job here and at Hull KR rugby club which he owns in effect is too much and he's left the club tonight.
"He was working well with Massimo (Cellino) but Adam Pearson has left the club, I've just had that confirmed."
The news is disappointing for Leeds as Pearson seemed a calm, experienced presence behind the scenes and had reduced Cellino's day to day involvement with club affairs.
The line appears to be that Pearson is taking a break, but it also remains unclear if he intends to return, or if Leeds will seek to replace him.
Former Leeds striker Noel Whelan gave his reaction, telling BBC Radio Leeds: "It's going to be difficult (for Pearson) with two high profile positions, but its a massive blow for Leeds."
Leeds had tempted Pearson away from a similar role at Sheffield Wednesday to bring him in back in May.
