Pilgrims snap up Red Devils duo
Both players arrive on three-month loan deals and Gray returns to Home Park after a spell on loan with the Pilgrims last season.
Central defender Chester, 20, had a stint on loan at Peterborough last season and is the current captain of Manchester United's reserve team.
Right-back Gray, 21, returns to gain further first-team experience and both players could feature for the Pilgrims in their away clash at Newcastle United on Saturday.
