I say fine him, maybe drop him to the bech, but not keep him off the pitch altogether, the clubs need for points is too important at this stage.
The thing is though if Carroll isn't starting tomorrow (if fit) then it pretty much just admits thats something's wrong at the club, lets get over that line first then see what happens, Carroll and Taylor don't look like playing in the same team again this season in anyway because of Taylor's injury, so no problems in that regard.
