The Football Association are carrying out an investigation to ascertain whether Mansfield Town striker Adi Yussuf urinated in front of opposition supporters.Plymouth Argyle fans reported the forward for allegedly urinating in front of them as he warmed up during the Stags' 3-0 loss at Home Park.

An anonymous fan told the Plymouth Herald: "During the first half of the match Mansfield substitute Adi Yussuf was warming up on the touchline right in front of the disabled zone where I sit with my friend.

"He said something to Plymouth Argyle substitutes Rooney and Purrington before walking over to the piece of disused land between the disabled zone and the Devonport End and took a wee.

"This was right in front of everyone in the disabled section.

"Myself and the lady who works in the refreshments area witnessed it as well as some others and we reported it to the stewards.

"They later took a statement and reported it to the referee."
