 More importantly, the Tigers were experiencing monetary disputes with the IRFU over allocations of revenue.After signing Frank Filchock, who had been suspended by the NFL due to gambling issues, the Tigers felt that the other teams in the IRFU should share in the payment of his high salary because they were benefiting from higher attendances when he was playing in their cities.After the IRFU refused, the Tigers made an arrangement with the ORFU and transferred to that league, with the Wildcats switching to the IRFU on April 9, 1948.
