Morrison has been sidelined since November with a knee injury but has now played in two reserve matches to build up his fitness.
Fellow defender Wayne Bridge is also on the mend but will not quite be ready to return from his knee problem.
Midfielder Danny Guthrie completes a two-match ban for collecting 10 yellow cards this season while Danny Williams (knee), Mikele Leigertwood (ankle) and Jem Karacan (cruciate) remain on the sidelines.
