Aveley boss Justin Gardner made three deadline day signings yesterday to boost the Millers play-off bid.
Goalkeeper Andy Hall has signed forms for the club, while also playing for Bethnal Green United in the Essex Senior League.
Hall has plenty of experience at this level, playing for Grays Athletic, Brentwood Town and Tilbury in recent seasons.
Another goalkeeper to join is 17-year-old Conor Trew, while his other deadline day signing was left back Karl Blake.
Blake made the switch to the Millers last season when Gardner first took over at Mill Field from Bethnal Green United.
The defender has been back at Bethnal Green this season, but the Aveley boss has opted to re-sign the player to add to the competition in the team over the final eight games of the regular Ryman One North season.
