National League side Forest Green Rovers have signed defender Ben Jefford on an 18-month contract from Welling.
The 21-year-old is eligible to face Macclesfield on Saturday.
Former Port Vale player Jefford has made 27 appearances for Welling this season.
"Ben is a good young player that we potentially feel is a league player," Rovers assistant boss Jamie Day told BBC Wiltshire. "He has gained some good experience."
