Coventry born Clarke, was expecting to be the U18's captain this season but he has featured in all the pre-seasons and has been given a two year professional deal.
On Sunday, Jordan made his Football League debut when he came on as a 62nd minute substitute against Ipswich Town.
Said Clarke to the club website: "I'd love to get a few starts under my belt, but it's early in my career. "My aim for the season is to get as many appearances as I can. It's all experience for me at the moment, and I just aim to do well for Coventry."
