Swindon caretaker boss Paul Bodin has expressed his anger over the behaviour of defender Alan Sheehan after his decision to go on trial at Preston this week.
Bodin left the Irishman out of Saturday's match with Oldham after the player's agent told Town's interim chairman Jeremy Wray of Sheehan's choice to try and earn a move away from the club.
The Robins are braced for several departures after being relegated from npower League One but Bodin has warned that anyone setting their sights on leaving will not be involved against Tranmere at the weekend.
He told the Swindon Advertiser: "We did not give him permission to sort something out and it is already sorted before we get wind of it.
"If his heart is not in the club and he is not going to give 100% then we don't want those type of players at the club.
"If players are going to stay at this club they have to be totally committed. I will speak with players this week and if anyone else is thinking about leaving in the summer then they will not be involved on Saturday."
