Plymouth midfielder Simon Walton has been placed on the transfer list after his red card in the defeat at Barnsley.
Walton, who has also been fined two weeks' wages, has been told he can leave Home Park after infuriating manager Paul Sturrock with his dismissal.
The Pilgrims went on to suffer a 2-0 defeat at Oakwell after Walton's dismissal for kicking out at Anderson De Silva, the fifth time in the 21-year-old's career he has received his marching orders.
Sturrock had spoken to the former Leeds, Charlton and QPR man prior to the incident against Barnsley, and with his warning not being heeded has decided to take what he feels is the appropriate action.
The Pilgrims boss told the club's official website: "I have had a discussion with Simon today and I have made it very plain to him how disappointed I was about the whole scenario.
"I had emphasised it to him [the danger of being sent-off], after watching video evidence from the last couple of games where there were certain incidents that could have turned into what happened on Saturday.
"He took no heed of that and, after careful consideration, I have decided to put him on the transfer list, and I have fined him two weeks' wages.
"The reason why this has been brought to a head today is the pre-warning I gave him over the last couple of games.
"He has taken no heed of it and that I can't legislate for, I can't tolerate or accept.
"There were several incidences in several games where he has been very close to tempting [the referee]. After taking the time to show him bits and pieces, and reiterate my thoughts on it, for it not to happen, I cannot accept.
"He has let all the players down, which is more important than anything else and I feel this is an appropriate course of action."
