Defender signs a one year contract.Kane played a full ninety minutes as the U's U21s drew 2-2 with Coventry City on Tuesday afternoon.
"It allows us to keep him at the club and watch his progress over that time, and we have plenty of games in the U21s for him to develop."
"Kane has signed a one year development contract with us," boss Tony Humes confirmed.
