The Welshman returns to strengthen a backline who conceded twice against Manchester United on Thursday.
The potential adjustment sees to the starting XI in place of Clement Lenglet.
Mason said he was pleased with Richarlison against United but when asked if he needed regular minutes to get back to his best, the interim boss talked up the importance of the squad.
“We've got a squad of players that we need to decide the best team to win a game of football,” Mason said.
“We felt Richy, with the profile of player he is, could help us and we spoke before about having a bit of anger and showing a reaction.
“I think Richy naturally is that type of player as he likes having a bit of physical contact and I was very pleased with his performance against United."
