We've still got a (albeit small) chance of automatic promotion; there's not a chance Challinor is holding players back for the playoffs. As he said himself in his post-match, we don't currently have a natural right-back and are making do with what we have, to the point of playing Jay Mingi despite him not being fit enough to play more than 45 minutes; if Knoyle is ready to play then he'd be playing, likewise Bate/Powell/other injured players.
