Davis, who was told this week he would be delisted by the Swans, may follow former AFL stars Ben Graham and Saverio Rocca in trying to make it in the US National Football League.
The Sunday Age newspaper reported that Davis kicked a gridiron ball for the first time this week in two sessions with Australian-based NFL scouts OzPunt in Melbourne. While most NFL punts have a hang-time of about 4.5 seconds, and Davis' best kick remained airborne for 5.12.
It was the first occasion Davis had kicked a football of any kind since injuring a knee in August.
OzPunt will distribute footage of the session to NFL clubs this week.
"It's something I've watched on TV and thought it may be something I could do," Davis said.
"There's a few different technique things that I've got to work on, but (OzPunt) were pretty happy and I met all the criteria the NFL scouts are looking for. I had one trip over to LA and loved it over there. It would be the opportunity of a lifetime to try something different."
OzPunt's Cameron McGillivray believed Davis could switch codes: "What impressed me was his ability to take his AFL kicking style and adapt it to the NFL style of punting in such a short time.
"By the end of the second day, he was hitting punts that would be well received by NFL coaches. He was getting five-second hang times, and he makes it look so easy.
Davis will now do more testing in mid-December before heading off to the US in March for possible trials with NFL teams.
But he said he hadn't given up hope of reigniting his AFL career and would nominate for the national and pre-season drafts.
"I think I've still got a lot to offer to the AFL, but now I've also got something to fall back on," he said.
"I can take a lot of heart out of what Stuey Dew accomplished this year. He was instrumental in Hawthorn's third quarter in the grand final."
