Scunthorpe United have accused Ipswich Town striker Pablo Counago of spitting at Andy Butler during the visitors' 2-1 win at Glanford Park.
Counago was dismissed in the second half, along with Scunthorpe's Jack Cork, after the Spaniard had earlier opened the scoring in Ipswich's 2-1 win.
Iron boss Nigel Adkins feels sympathy for his midfielder Cork, who was sent off in the subsequent melee, and was critical of Counago's conduct.
"Counago spat in Andy Butler's face," claimed Adkins. "There is no place for that in English football, it's a disgrace.
"From what I'm led to believe he then slaps Jack Cork in the face.
"Jack puts his hands up and the referee sends them both off. Poor Jack is crying his eyes out. We feel for the lad."
Ipswich boss Jim Magilton has confirmed he will take action, if it is confirmed Counago spat at Butler.
Magilton said: "The sending off was a very unsavoury incident, but it will be dealt with internally.
"If I see that Pablo Counago has spat on a fellow pro it will be dealt with very harshly."
The result kept Ipswich in the play-off hunt and Magilton felt his side could have won by a greater margin.
He added: "It was a great result for us. I thought we were good value for 1-0 at half-time. Had we taken more care of the ball, and with a little bit more quality, we probably could have gone in two or three up.
"Scunthorpe adjusted to the sending off better than we did, that was their best period. They put us under an awful lot of pressure and we didn't cope with it very well."
Still in it
Though Scunthorpe are now six points adrift of safety, Adkins remains upbeat about the club's prospects of survival.
Adkins said: "We are where we are, but I have looked at the league table and we're still in it.
"We are only six points off Sheffield Wednesday and Leicester and we've got them both to play in the next few games. We are right up against it, but have still got to keep believing."
