Sudbury suffered their heaviest defeat for many years as they went down 90-0 away at Tring in the London League One North on Saturday.
As well as missing a number of squad members through injury, Sudbury were not helped by the fact they had to play the majority of the second half with 13 players due to ill discipline.
It means that Sudbury, who have lost all six of their league matches this term, remain rooted to the bottom of the table on minus three points after they fielded an illegible player.
In National League Two South, Bury St Edmunds lost narrowly 41-36 at Henley Hawks.
Bury held a 24-15 lead heading into the break, but a poor second-half display saw them come unstuck.
Elsewhere, injury-plagued Diss moved to the top of the London League Two North East division courtesy of their 30-15 home victory over Old Cooperians.
Ely, Stowmarket, Thetford and Halstead also picked up wins.
