Bolton Wanderers boss Ian Evatt expects his side to be hit with sanctions after crowd trouble marred today's derby loss against Wigan Athletic.
Wanderers lost 4-0 at the University of Bolton Stadium this afternoon.
The Latics went ahead early on thanks to Will Keane's opener, while James McClean's brace and Callum Lang's finish ensured an emphatic win for the visitors.

But off the pitch in the second half, there were crowd issues in both home and away areas.
Supporters in the away end where the Latics fans were housed removed some of the advertising displays from one of the stands, which then had to be collected by stewards and police.
And midway through the second half when Wigan's Max Power was preparing to take a corner, there was a stoppage in play when Wanderers supporters appeared to throw objects onto the pitch, which then had to be cleared.
A couple of flares were also thrown onto the pitch from both sets of supporters.
Both teams have issued statements and launched investigations into the matter.
Both managers had their say on the issues after the game and the Bolton boss foresees his club being hit with sanctions as a result.
Evatt said: â€œThe game itself, weâ€™ve let our support and fanbase down and I must say, that incident aside, they didnâ€™t boo us, they didnâ€™t get on our backs and I thought they were excellent.
â€œBut the minority always spoils it for everybody else and we canâ€™t and shouldnâ€™t have to see that on a football pitch. We understand that theyâ€™re annoyed. We understand theyâ€™re frustrated, but when that happens, all youâ€™re going to do is harm the football club and ourselves.
â€œThereâ€™s probably going to be sanctions off the back of that. I hope we can identify who has done it. We take on board and really apologise for our own performance, but we canâ€™t accept that on a football field either.â€
Wigan counterpart Leam Richardson was unsure what happened and and did not comment on the matter.
He said: â€œIf Iâ€™m honest I donâ€™t really know what (happened). Weâ€™re quite far away arenâ€™t we, so I thought the officials and the police managed the game and the fans ever so well today. Apart from that, I canâ€™t really comment because I wouldnâ€™t know what I was commenting on.
â€œItâ€™s a derby game. When Bolton came to our stadium I thought they supported their team fantastically well, as we did at our place, and thatâ€™s all I saw today. I was obviously watching the game as much as I can because thereâ€™s that many moving parts, itâ€™s tough.â€
