"They took the ascendancy in the last 15 minutes of the first half, scored the goal from a set play which is obviously disappointing then it became a real battle and our players tried to get something from the game.
"It wasn't pretty and we couldn't quite do it which was disappointing."
The Yorkshire side are seventh in the league table, one point behind Nottingham Forest.
