Sunderland are looking to give their youngsters first-team football opportunities.
Sunderland are looking to secure temporary moves for some of the standout players in their Under-21 side.
According to a report in the Sunderland Echo, a quartet of youngsters are due to depart the Stadium of Light this month as the club looks to hand them the opportunity to gain first-team football.
McNamee, a commanding centre-back, is expected to complete a switch to Boston in the next few days, following in the footsteps of a number of other Black Cats players in recent times.
Meanwhile, Dixon is wanted to play a first-team role in net for Alfreton Town, who are currently fighting against the drop down in the Conference.
Oliver is set to move to the highest placed team, with Blackpool taking a keen interest in signing the central midfielder.
The Tangerines are desperate for additions after heading into the season with a very depleted squad and Oliver should benefit from playing regular Championship football if he does sign at Bloomfield Road.
