Kent spent the first half of the season on loan at the Sky Blues.
The winger has made one first team appearance since he returned to Anfield, in a third round FA Cup tie against Exeter City where he played for an hour before being substituted.
Mowbray said: “There’s no option to get him back. I would think it’s a stepping stone in Ryan’s development and we need to move on."
Liverpool's policy about loaning out players appears to have taken a shift since the arrival of Klopp at the club as he wants to focus on developing the younger players as a team rather than focussing on their individual development - so when the opportunity arises they can slot into the Liverpool first team with ease rather than being away from the club and learning their trade in a different way to the parent club.
As a result, it would be hard to see another loan offer for Kent entertained by those at Anfield right now, but it will be interesting from the start of next season to see just how many of Liverpool's younger players will be allowed to leave the club on a temporary basis, and the reasons behind it, because there is a feeling it could be a lot less than in seasons gone by.
