Leeds boss Neil Redfearn admits he is low on options.
The 22-year-old was on the losing side as a jaded Leeds were well beaten 2-0 at Brighton, and Sloth was substituted after 59 minutes.
He had made only 22 touches, and while making four tackles, created no goalscoring opportunities and struggled to have a telling impact on the game.
Seven starts out of a possible 33 this season in the league tells it's own story about how the summer signing has failed to win favour, and after the game Neil Redfearn did not exactly give a ringing endorsement of the Dane.
He told BBC Radio Leeds: "To be fair to Casper he worked hard as he could, but it didn't quite happen for him.
"As soon as Casper plays, that's the last recognised midfield player out there on the pitch. You've got four strikers, two defenders and a goalkeeper, and the two you leave at home Adryan and Montenegro are attacking type players anyway."
Leeds have a lack of options in terms of midfield cover, with loan signing Granddi Ngoyi injured, and Michael Tonge sent out on loan.
Sloth may as a result get more chances, and earn more opportunities in the side on merit, but he has to start seizing those he gets given, whether by default or not.
