The 26-year-old joined from Leeds on a free transfer in the summer after scoring 31 goals in their promotion to the Championship.
However, he has found the net just once at his new club - in the Carling Cup - and has failed to establish himself in the first team.
However, after impressing for the reserves in the 5-0 win over Blackpool, in which he scored, second-string boss Alan Stubbs has backed the striker to come good in the top flight.
"We wanted him to play on the defender's shoulder. A lot of his goals at Leeds came from him running on to things. Defenders don't like it when you play just on the shoulder," he said.
"On another day he could have had three or four. But he scored and hopefully he'll take confidence from that because he admitted he was probably a bit rusty."
