Sheffield Wednesday boss Brian Laws has urged supporters not to boo Francis Jeffers, saying 'enough is enough'.
Jeffers has been on the transfer list at Hillsborough since being sent off for violent conduct in the Carling Cup defeat by Port Vale in August.
He made his first appearance since that red card as a late substitute in last week's home defeat by Preston, but his introduction was jeered by Owls fans.
Laws is still looking to offload the England cap, but does not believe the striker should suffer abuse from the Wednesday faithful.
"He is going to need broad shoulders if the fans are unhappy, but I also think enough is enough," Laws told the Yorkshire Post.
"Nobody wants to hear booing for your own player when he is walking on the pitch - it doesn't just affect the player, it affects the whole team.
"He is our player until things change and he goes somewhere else.
"It would be easy to isolate someone, but he's a good player and if we do that, we are a man down. When you are chasing a game, you want a player who is one of the better finishers at the club to come on and try and get a goal.
"I am not saying Francis is a great lad in terms of what's happened so leave him alone, but I am saying enough is enough otherwise there is no point putting him on the bench and that would be a crying shame."
