Richard Chapman will definitely play for Hunslet after recovering from an arm injury.
March has warned Leigh not to expect a comfortable ride. He said: “Our performances against Halifax and Barrow prove we can play at this level.
“If we get through this week then you never know what might happen. We’ve got the experience within our squad; we’ve just got to put things together on Sunday.”
Centurions Assistant Coach Paul Rowley said: “Hunslet seem to have gone on a good run recently and they’ve improved throughout the season.
“A lot comes off the March brothers and it’s a small pitch there. They’ll be trying to unsettle us and put us off our game, but hopefully we’ll have a bit too much experience and we’ll get back to what we do well.”
