Plymouth Argyle have placed Marcel Seip on the transfer list and fined him two weeks' wages after he refused to be a substitute on Saturday.
The Dutch centre-back was named as one of manager Paul Sturrock's replacements for the match with Charlton, but decided not to take his place on the bench on what was his 26th birthday.
Seip has been a regular in the Argyle starting line-up this season but was overlooked by Sturrock in favour of Russell Anderson and Krisztian Timar against the Addicks, who won the match 2-1.
"I am fining Marcel two weeks wages because of his actions," Sturrock told the club's official website.
"It is appropriate to put him on the transfer list as well.
"I also feel that now is the right time for Marcel to get his hernia problem fixed."
