Hartlepool Take Sunderland's Harrison On Loan.
The defender had been training with Ronnie Moore's men this week and has done enough to be offered a loan deal that will last until the end of the season.
The Black Cats had already said that the player was clear to sign for the League Two outfit, but Moore wanted to see the player in match conditions before making any decision over his future.
The deal has now gone through so Moore must have been able to resolve the situation with his displays on the training field.
Harrison will be in the Pools squad for Saturday`s game against Wycombe.
