During the sixth round of fixtures, which were played on 7 September 2013, Portadown defeated Ballinamallard United 11–0 at Shamrock Park.
This equalled the post-war record for the biggest win in the top-flight, which was set 47 years earlier in the 1966–67 season when Distillery defeated Bangor by the same scoreline in November 1966.
This was confirmed on 12 April 2014, after Warrenpoint Town defeated Dungannon Swifts 4–0 to leave Ards 10 points adrift in 12th place with only three fixtures remaining.
The other newly promoted side, Warrenpoint Town, played some of their home fixtures at Dungannon Swifts' ground, Stangmore Park.
† Darren Boyce scored 12 goals for Dungannon Swifts while on loan from parent club Coleraine, before transferring to Ballymena United in January 2014.
The play-off did not take place this season because Bangor, runners-up of the 2013–14 NIFL Championship 1, did not possess a licence to participate in top-flight football.
