Fleetwood head coach Joey Barton has "emphatically" denied all allegations made against him following his side's match against Barnsley on Saturday.
Barnsley have lodged an official complaint with the EFL and the FA, with their statement saying there was "an alleged incident at the conclusion of the match on Saturday 13th April between Joey Barton and Daniel Stendel".
South Yorkshire Police were expected to speak to Barton on Wednesday in relation to what they described as "reports of an assault".
However, Barton tweeted on Thursday morning: "With regards to the alleged incident on Saturday following our game against Barnsley, I emphatically deny all the allegations made.
"Given this matter has not been formally closed, it would be inappropriate for me to make any further comment."
Barnsley said that Stendel suffered facial injuries during the incident, but that he is now "OK".
Sky Sports News understands Barton is expected to be in the dugout for Fleetwood's game against Peterborough on Friday.
On Wednesday, South Yorkshire Police bailed a man who was arrested on suspicion of racially aggravated assault and a racially aggravated public order offence at Oakwell on Saturday.
Their investigation relates to an incident which took place following the match between Barnsley and Fleetwood, which the home side won 4-2.
