Sorry francis your bench is
As per the rules since the start of the season like a few others, you cannot swap players out of your 17. They must stay the same.
So Sloan stays. It is Round 15 this week which means 10 more rounds to go before the season ends. You have your 4 subs and 4 trades with any member of your current playing 13.
But no you picked Sloan at the start of the season, and he has to stay in your 17. As do all the other players.
