PAUL Cullen has warned Wolves fans not to expect miracles from Jon Clarke or Michael Sullivan if they are require to kick goals on Sunday.

Lee Briers and Chris Bridge are Wolves' first-choice goal-kickers but both are big injury doubts for the Hull KR game, so Clarke and Sullivan have been practising their kicking in case they are called upon.

But Clarke has only kicked one goal in his six-year Wolves career and Sullivan is yet to get off the mark, so Cullen is not putting too much pressure on them.

"Jon Clarke and Michael Sullivan have practised this week and we'd like to think when we score we can get them in a kickable position," said the Wolves boss.

"No one can expect any of our third or fourth choice kickers to kick anywhere near as well as Lee Briers or Chris Bridge."
