West Yorkshire Police are continuing their investigation into Saturday's tunnel bust-up between Leeds and Doncaster at Elland Road.
• Leeds 3-2 Doncaster
Leeds won the derby clash 3-2 in injury-time and after the final whistle Doncaster striker El Hadji Diouf and Leeds forward Ross McCormack appeared to clash.
Several police officers were seen to rush down the tunnel after the players had left the pitch.
A police spokesperson said: "Following the final whistle at the Leeds United versus Doncaster Rovers game there was a small disturbance in the tunnel involving both teams.
"Officers swiftly dealt with the incident and there were no injuries or arrests. Both teams are working with the police and any necessary action will be taken in due course."
Leeds came back from two goals down to snatch a winner in the 10th minute of stoppage-time in a highly-charged finish.

Both clubs have refused to comment.
