Earlier this evening, it emerged Warburton had resigned.
But now it is suggested Warburton has categorically denied handing in his resignation.
After a poor run of form which sees Rangers third in the Scottish Premiership, the former Brentford boss it was thought had quit along with assistant manager David Weir and head of recruitment Frank McParland.
Warburton conducted his normal Friday press conference duties ahead of Sunday’s Scottish Cup tie against Morton (3pm).
But now it is understood that Warburton was unaware that the statement put out.
And he is thought to be consulting his legal team.
A club statement previously read: “Rangers has accepted the resignations of manager Mark Warburton, assistant manager David Weir and the club’s head of recruitment, Frank McParland.
“Rangers believe the management team have not reached the targets set.
“The board is very appreciative of the good work previously done by the management team but believes it had no alternative.
“Our club must come first and absolute commitment is essential.
“It is important that Rangers has a football management team that wants to be at the club and that the board believes can take the club forward to meet our stated ambition to return to being the number one club in Scotland.
“We are clearly short of where we expected to be at this time.”
