He credited Vigar’s family with “making everyone come together” and persevere as a team.
“The biggest thing for all of us now is Billy’s family and doing right by them,” he said.
Mr Rutherford added that the West Sussex club, which had postponed its previous match against Lewes following the incident, had invited Vigar’s relatives and fans to “join in with paying tribute to him” at Saturday’s game.
A minute’s applause was held for the late player before kick-off and his number nine shirt was displayed on the pitch.
“He was a quiet lad and one of the nicest I’ve met in the sport,” Mr Rutherford added.
“Billy was just starting to come out of his shell and his family told me he was loving life and playing football.
“It’s all just so unfair.”
Darin Killpartrick, the first team coach, added that Vigar would “never be forgotten”.
