Ryan arrived at Oakwell from Swansea City in January of 2017, signing a two-and-a-half-year deal.
He is a Welsh international and can play up front as well as in his natural position out wide.
Having made just a handful of appearances during the 2016/17 season, Hedges will have been hoping to feature much more prominently for the Reds with his injury problems finally behind him.
And his 2017/18 season got off to a flyer, scoring three goals in the first month of the season including a stunner to see off Nottingham Forest at Oakwell.
Hedges also made his full debut for Wales in November, coming off the bench against Panama.
