Both players made an impact at the weekend against Hartlepool, with Ahkeem scoring both goals in a 2-1 win against Pools.
The visitors had taken the lead with a breakaway goal in the first half, but the Mariners piled on the pressure and Ahkeem ran through the Pool's defence and equalised at the second attempt. And then, with only minutes remaining in the game, the trialist frontman linked up well with Brandon Buckley, before cutting inside his marker and finishing powerfully past the Pool's keeper.
Neil Woods' side are next in action this Saturday when they face York City at Cheapside (11am).
