Morrison said: “I’m delighted to welcome Matt to the Albion, as we prepare for the challenge of keeping the club in the Championship.
“Matt is a first-class coach with an outstanding character, and I am convinced he will help us turn the tide on what has obviously been an incredibly poor season to date.
“Together, with Damia and Boaz, we must rebuild confidence in the players on the training pitch, so we are equipped to deliver under pressure in matches.
