The Phobians have been hit by a squad crisis with up to 5 first team players away on international duty at the 2023 CHAN tournament in Algeria.
Kuka, 20, was farmed out to the Pride of the North before the start of the season by the Rainbow club and has scored 6 league goals in 10 games.
Meanwhile, Benjamin York is the leading scorer for the former African champions with just 3 goals from 8 games.
With striker Daniel Afriyie Barnieh set to exit the club at the end of the tournament in Algeria, the Phobians desperately need a replacement and the lanky forward has now become the heir apparent at the capital club.
However, according to the reports as given by ace broadcast journalist Bright Kankam Boadu, RTU are unwilling to release the striker back to Hearts as the loan agreement between the clubs does not contain a clause that could get the Phobians recall the forward from the agreement.
In this regard, the Tamale-based club are asking Hearts of Oak to pay a compensation to them before they agree to release their player back to them.
