Tozer made his debut the following day in the "Cobblers" third round League Cup win over Liverpool, and the following Saturday scored on his Northampton League debut in the 2–0 win over Bradford City. He was sent off in the game at home to Hereford United for violent conduct, which resulted in the Cobblers delaying renewing his loan until after he served his three-game ban. Tozer had his loan extended twice: the first extension came until 9 January 2011 and the second extension came until the end of the season. He went to make 31 appearances and scoring twice this season against Aldershot Town on 19 February 2011 and Morecambe on 7 May 2011.
