Taken from the bspa site:
"Rathbone admitted a couple of attempts to make a signing this week have not come off. Adam Ellis, who impressed for the GB Select team as the curtain went up on the new season last Sunday, was unable to take up an offer from Panthers as it would have made him ineligible to race in the National League for Birmingham."
Surely the fact that Ellis rides on a friday, the same day as Lakeside ruled that out?
