Adi Yussuf is alleged to have relieved himself in view of fans in the Stags' loss to Plymouth Argyle, with the FA now investigating.
The Football Association (FA) is looking into allegations that Mansfield Town striker Adi Yussuf urinated in view of supporters during a League Two match against Plymouth Argyle.
Yussuf is reported to have relieved himself during Saturday's match at Home Park, which ended in a 3-0 win for Plymouth.
The Plymouth Herald received an account of events from a witness the newspaper stated wished to remain anonymous.
"During the first half of the match Mansfield substitute Adi Yussuf was warming up on the touch line right in front of the disabled zone," the unnamed fan told the newspaper.
