Redruth boss Dave Penberthy hopes the Cornish Pirates do not recall his influential fly-half son Aaron ahead of Saturday's derby at Launceston.
Penberthy junior has scored 96 points in the last four games as the Reds have gone on their best run of the season.
But he is on a dual-registration deal from the Pirates, having signed for the Championship side in September.
The Pirates face Cross Keys in the British & Irish Cup on Sunday and Penberthy fears his son may be picked.
The Pirates have injury problems at fly-half with Jonny Bentley and Ceiron Thomas both injured.
Exeter's Myles Dorrian has been on loan at the Mennaye as cover, but Penberthy is unsure whether he will be involved on Sunday.
"I'm hoping that the situation won't change and he [Aaron] will be with us," Penberthy told BBC Radio Cornwall.
"But when you've got players that are on loan, those sort of circumstances can change at a drop of a hat.
"I did speak with (Pirates coach) Harvey Biljon last week and it's obvious that it depends on their situation and their loan signings."
Redruth have achieved bonus-point victories in the last four matches, including an impressive 37-22 win over high-flying Worthing last week, and Penberthy says his son has been crucial to that success.
"We are looking to him to step up to the mark and he's certainly been very good over the last few weeks and scored a bucket load of points," he said.
"He's a key player for us and I just hope that he's going to be available and not taken back to the Pirates for their British and Irish game."
