Shane McCabe says it was a "very difficult decision" to leave Premiership club Portadown to resume his Fermanagh GAA career.
"I've never dedicated a full year to Fermanagh and I feel I've only a couple of years left at county level, so now is the time to do it," said McCabe.
"Peter Canavan is obviously a big plus and it's a good coup to get a manager of his calibre.
"I've met him a couple of times and he has impressed me."
"He has made a big impression on me with everything he has said so I'm willing to put all my focus into Fermanagh.
"Unfortunately that means that I'm unable to play for Portadown, and it's a decision that I've thought long and hard about.
"It was a difficult conversation to have to tell Ronnie McFall and he wasn't too happy, but he accepted it reasonably well.
"I've experienced all the highs and lows in the Irish League - league championships, cup finals, Setanta Cup finals and relegation, and it's something that's still a part of me.
"I feel Portadown have the team to push for the title and I wish them all the best."
Responding to comments by McFall that he had breached his contract, the 30-year-old said he hoped the issue would be "sorted out".
"I made Ronnie aware that I was leaving and kept him informed, so I'm not sure where the problem lies.
"If the scenario arises that I may be of some help in the autumn, then we will see what develops."
McCabe added that he feels he has "a big part to play" in improving the Erne county's fortunes this season, beginning with this weekend's clash with London at Ruislip.
"It is up to us to get out of Division Four and build for the start of the Championship.
"Peter has brought a huge sense of professionalism with him and hopefully with some training under my belt, I'll be able to nail down a starting jersey."
