It is a double fitness boost for manager Michael Beale who has been unable to call on Colak for his first four matches in charge, while Morelos limped out of the 3-0 win over Motherwell on Wednesday.
Morelos scored the opener in that match and looked more like his old self, but was replaced in the second half due to feeling tightness in his hamstring, while Colak has not played for Rangers since the 1-0 win over Hearts on November 9.

Hide AdBeale confirmed: "Alfredo Morelos has trained and should be available along with Colak. Roofe is touch and go, he would definitely be available if Morelos doesn't make it."


Roofe has not been included in a matchday squad since October 22 and has managed only two appearanes this season after injuring his knee in pre-season.
