Yaxley had hoped to host the Rocks on their artificial surface at Leading Drove again on Sunday before the match was pencilled in for midweek.
Newby, pictured, suffered a suspected dislocated elbow near the end of the First Qualifying Round tie against the United Counties League's Cuckoos. The match was abandoned with three minutes left to play before the 25-year-old was taken to hospital by medics.
Back at Rookery Hill for a third time in his career, free-scoring Newby helped AFC Sudbury win the Ryman North title and has also impressed at Grays Athletic and Witham Town.
Something of a ‘prodigal son’ to Rocks boss John Coventry, who has nurtured his talents since he was a boy, Newby has had many of his best football moment in a Rocks shirt.
