Coltman reaches 'Landers milestone
Coltman made his debut in 2013 and has become known as a hard-working, uncompromising hooker.
Injuries have forced changes to the pack that defeated the Lions last week, with lock Joe Wheeler and versatile loosie Dan Pryor ruled out due to concussion. Luke Whitelock is also side-lined with a knee injury.
After a week's rest, Tom Franklin returns to lock and co-captain Shane Christie starts at openside flank, joining Elliot Dixon and a recovered Liam Squire in the back row. Mark Reddish is back from injury to take his place on the bench.
The only change in the backline sees Ryan Tongia coming in for an injured Patrick Osborne, giving Tongia his third cap.
Unavailable due to injury: Waisake Naholo (leg), Marty Banks (knee), Fumiaki Tanaka (calf), Tei Walden (concussion), Joe Wheeler (concussion), Dan Pryor (concussion), Josh Hohneck (head cut), Luke Whitelock (knee), Patrick Osborne (Hip).
