Returning Essendon player Travis Colyer says he felt like an 18-year-old again walking into the club for the first time in 12 months upon his return.

Colyer was one of 34 current and former Bombers suspended for one-year for his part in the club's 2012 supplements program.

The 25-year-old, who has played 57 games, said he did not know what to expect walking into what felt like a new environment after a year out of the game.

โ€œIt was almost a little bit like that feeling, not really knowing what to expect because itโ€™s a new environment with a new coach (John Worsfold), although obviously we had him for a little bit (before being banned),โ€ Colyer said on SEN Radio on Friday morning.

โ€œIt was a little bit nerve-racking but the support that weโ€™ve had from not just the staff and the football department, but the fans as well has been overwhelming.โ€

Despite the difficult circumstances surrounding his 12 months off, Colyer said his time away from the game helped "reinvigorate" him leading into the 2017 season.

โ€œFootball is such an intense and consuming environment, any opportunity you can get to have some time away, not in the circumstances that you want, but itโ€™s definitely reinvigorated me,โ€ he said.

โ€œMy next development is hopefully to play a little bit more inside mid. Iโ€™ve been working hard on my stoppage craft."
