Wolves manager Stale Solbakken called on his side to "toughen up" after their winless run extended to five games with a 2-1 defeat at Hull.
Wanderers were expected to be front-runners for promotion this season, but they are currently languishing in mid-table after their fifth loss on the road.
However, Solbakken was encouraged by his side's display at the KC Stadium and insisted they were unfortunate to leave empty handed.
"We were a little bit unlucky," he said. "They scored one brilliant goal, I don't know how their second one went in.
"Defensively we were very solid all through the game, we didn't really let them have many other chances and we had some chances to make it 2-2.
"We're having a bad spell at the moment, but we have to toughen up and don't feel sorry for ourselves and keep on playing.
"It's a crazy division at times and we're not doing well enough in it, we're not picking up enough points and we have to improve in that department."
