The talented midfielder picked up a knee injury whilst on loan with Stevenage.
But in recent times things have been difficult for Jebb. He had recently struggled to make his way into the Arsenal under-21 side as other young players seemed to overtake him.
He took the brave step of going out on loan in October, joining Stevenage Borough in League Two. He originally joined on a one-month deal but that was subsequently extended.
His time in Hertfordshire was impressive. He played four times in the league and also featured in the FA Cup. He even managed a goal against Bishop's Stortford in the Herts Senior Cup competition.
Unfortunately Jebb suffered a nasty knee injury which brought his loan spell at the club to an end.
He was set for six to eight weeks on the sidelines but that was clearly not the case.
He only made his comeback this evening, as Arsenal under-21s took on Blackburn Rovers.
He seemed happy with his comeback, posting this Tweet celebrating a return to action after 13 weeks out.
Now he will be hoping to push on and become a member of the Arsenal first-team, although his future is looking increasingly likely to be away from the club.
