LEIGH Centurions will be without Blake Wallace for Friday's Super League clash with Castleford Tigers.

He left the field midway through the first half as Leigh gave up an early 18-0 lead in their 36-18 loss to Huddersfield Giants in the Challenge Cup third round at Leigh Sports Village.

"Blake has a head injury, so he'll not be available on Friday," said Duffy.

The loss of Wallace left Duffy with an amount of team shuffling to do.

"I had to play Jordan Thompson in the back row, and Ben Hellewell who was in the back-row in the centre for most of the game and move Craig Mullen to full-back," he said.

"It was a big disruption but we should be able to cope with that, others do."
