Alex Beck netted a late consolation as Boston Town finished their season with a 2-1 defeat at Cogenhoe United.
The Cooks netted a goal either side of the interval to take a 2-0 lead before Beck struck to give Lori Borbely’s side some hope in the 82nd minute.
However, United held on to avenge last month’s 1-0 defeat at the hands of Boston.
Town currently sit 12th in the UCL Premier.
Although they have played all their matches, Desborough could still knock Boston down a place if they can claim four points from their final two contests.
