Will Hoskins's late winner on his Exeter City debut has secured victory for the Grecians over Yeovil Town on the opening day of the 2015-16 season.
Exeter led 2-0 at half time over the side who finished bottom of League One last season, but were pegged back to 2-2 through goals from Marc Laird and Matt Dolan before substitute Hoskins clinched it.
Another relegated side, Notts County, started League Two life with a 2-0 win over Stevenage thanks to goals from Curtis Thompson and a late Mawouna Amevor strike, before Amevor was sent off for an injury-time clash with Tom Hitchcock, who was also dismissed.
Cambridge United will end the opening weekend of the season at the top of the table after a comfortable 3-0 victory over Newport County, while a double from Kyle Bennett helped Portsmouth overcome Dagenham & Redbridge by the same scoreline.
Stephane Zubar's own goal rounded off a miserable day for York City, who lost 3-0 at Wycombe Wanderers, and there were 2-0 wins for Plymouth Argyle away at AFC Wimbledon and Hartlepool at home to Morecambe.
