[74] A week later on 2 December 2012, he scored the winning goal in the third minute of injury time as the Dons defeated AFC Wimbledon 2–1 in the Second Round of the FA Cup.

In the 2013–14 season, however, Otsemobor dropped to third choice right back, as a result of focusing on development of youth at Milton Keynes Dons.
