Grounds, 22, has already recorded 27 appearances for the Teessiders and has previously enjoyed two loan spells at Norwich.

The left-back - the club's sixth summer signing - says he is looking forward to his loan move north to Edinburgh.

Grounds said: "I've heard a lot about the SPL from the Scottish lads at 'Boro and I'm keen to get playing for Hibernian. It looks like an exciting league and a great club to be part of."

Manager John Hughes said: "Jonathan is a talented player we've kept tabs on for a while now and I'm delighted to have secured his services, even for a short period.

"He's young, committed and provides great competition in the team. I'm really looking forward to getting him working with the squad."
