SUNDERLAND RCA are among four Northern League clubs interested in possible promotion to the Evo-Stik League.
The Meadow Park men are enjoying their best ever season in the First Division, sitting three points clear at the top, albeit having played three games more than West Auckland.
Dunston UTS, Whitley Bay and Bishop Auckland have also formally expressed an interest in promotion, with a top-two finish a requirement, along with their ground passing an Evo-Stik League inspection.
The clubs can withdraw their applications further down the line.
Defending Wearside League champions Ryhope CW, Willington and Redcar Athletic have all registered an interest in moving up to the Northern League, but must finish in the top two to qualify.
