Barnsley have issued a formal apology following heated exchanges between its players and the club's travelling fans following their 5-0 weekend defeat at Huddersfield Town.
The club launched an immediate investigation into the incident at the John Smith's Stadium on Saturday when midfielder Stephen Dawson and winger Brek Shea responded to a section of angry supporters.
Barnsley slipped to the bottom of the table after their biggest defeat of the season and Dawson became involved in a passionate row with one supporter, while USA international Shea is alleged to have made an offensive hand gesture.
The club said its enquiries into Shea's involvement will continue until after the player has returned from international duty.
A club statement read: "Barnsley Football Club would like to apologise to its supporters for incidents further to the full-time whistle on Saturday at Huddersfield Town's John Smith's Stadium.
"As a club, we do not condone any provocative actions from any of its employees and would like to further apologise for any offence caused.
"Stephen Dawson has apologised unreservedly for his actions and will be making a substantial donation to Barnsley Hospice as way of an apology.
"In relation to an alleged incident concerning Brek Shea: the matter is currently under investigation and a further statement will be made upon Brek's return from international duty.
"Having the backing of our supporters at Barnsley Football Club is of paramount importance, especially as we head into the final months of our current campaign. Supporters are the lifeblood of the club and are the one constant throughout.
"Once again the club would like to apologise unreservedly for any offence caused and assure supporters such actions will not be repeated.
"Barnsley Football Club would like to thank its fans for their continued support and assure everyone that appropriate action will be taken where necessary."
Irishman Dawson has made his own personal apology for his part in the incident.
The former Leyton Orient midfielder said: "Firstly I would like to apologise for my actions on Saturday.
"My emotions were high and I shouldn't have reacted the way I did.
"I'm really disappointed with what was said to me, but I need to be professional enough to take that.
"The fans have paid an awful lot of money to come and see us and to lose 5-0, I can understand their frustrations and disappointment.
"I can only apologise and assure all the supporters it won't happen again."
