Oxford beat Cambridge in a Boat Race for the fifth time in the last seven years on the River Thames on Sunday.
The Dark Blues took an unassailable lead five minutes in following a collision in Cambridge camp, the BBC reported.
A clash of oars saw Cambridge's Luke Juckett briefly fall from his number two seat, which was taken advantage of by the Oxford.
Oxford, who won the race by almost 11 lengths, now trail 81-78 with one tie in the series.
There were three Olympians in their Oxford's crew - Canada's Beijing 2008 gold medallist Malcolm Howard and London 2012 bronze medal winners Constantine Louloudis of Great Britain and New Zealand's Storm Uru.
Earlier, the Dark Blues were pegged back, and Cambridge led by one-third of a length as the boats passed Fulham's Craven Cottage football ground but after the collision, Oxford gained the lost ground.
