Wealdstone have handed a first-team contract to Dean McDonnell on the back of his recent performances.
The decision came after he helped guide the reserves to a 3-0 win over Harrow Borough in the Capital League President's Cup.
First team manager Gordon Bartlett said: “This is a reward for the way Dean has developed as the season has progressed”
The Stones have allowed Sean Cronin to join Ryman Premier League side Grays for the rest of the season.
Cronin has struggled for pitch time in recent weeks and made the decision to drop down a division in order to get some games.
Bartlett added: “We totally understand Sean’s frustration at not playing at present. Sean really wants to finish the season well but we cannot guarantee him games so the best solution for all parties was a loan that also helps Mark Bentley in his quest for the play-offs.”
