The midfielder hasn't been involved for the Reds since his late cameo in Michael Carrick's very first game, the 2-0 derby win over Manchester City in January.
Mount had a late goal disallowed against Pep Guardiola's side and was then an unused substitute for our 3-2 victory at Arsenal.
Mason unfortunately picked up an injury during training the following week, but Carrick has revealed that our no.7 is back with the squad at Carrington and approaching first-team football again.
“Mason’s back with the group, which is fantastic,” Carrick said.
“He’s an important player for us, Mason, and to have him back and involved is a good step for us, definitely.
