Great Britain international Matt Diskin has returned to Leeds Rhinos squad for Monday's trip to high flying Salford City Reds. Diskin missed Thursday's defeat to Bradford with an ankle injury but has been named in Tony Smith's initial 20 man squad for Monday afternoon's crunch fixture. There is also a possible debut for Mark O'Neill after his recovering from a shoulder injury suffered in pre-season. The NRL Champion played for the Rhinos Senior Academy last weekend and was in the 20 man squad for the Bradford game before being ruled out. However, there is some bad news for the Rhinos with Chev Walker (knee) and Chris Feather (groin) both ruled out of the trip to Salford. Walker is expected to be out for a fortnight whilst Feather will miss four weeks. Nathan McAvoy has been named in the 20 man squad and could face his former club whom he played 144 times for in two spells at the club, scoring 78 tries. The 20 man squad in full is: 1. Richard Mathers 2. Scott Donald 4. Keith Senior 6. Danny McGuire 7. Rob Burrow 8. Ryan Bailey 9. Matt Diskin 10. Jamie Peacock 11. Ali Lauitiiti 12. Gareth Ellis 14. Shane Millard 16. Willie Poching 17. Mark O'Neill 18. Jamie Jones-Buchanan 20. Nick Scruton 21. Carl Ablett 22. Ian Kirke 24. Nathan McAvoy 26. Danny Williams 27. Ashley Gibson
