Crowley, who was the AFL's standout run-with player in 2012, suffered a torn pectoral muscle in December and has been on a restricted training program for six weeks.
The 28-year-old did not require surgery, but he has been kept out of all football drills and only recently progressed into contact work.
Still, the run-with specialist is confident he will be available for Fremantle's opening NAB Cup matches against West Coast and Geelong at Patersons Stadium on February 16.
"I’m just ticking the last few boxes before I get back into main training," Crowley told fremantlefc.com.au.
"Hopefully you’ll be seeing me on the track soon and I should be able to go in the next couple of weeks for the start of the NAB Cup.
"The good thing with doing a pectoral muscle is that you’re still able to run, so I’ve been able to keep really fit throughout the summer.
"I feel like I’m ready to go now, but they (the club's fitness staff) are making sure I get those last few indicators right before giving me the green light."
Crowley, who faced an uncertain future at the end of 2011, revived his career spectacularly under coach Ross Lyon last season, playing every game and routinely shutting down the opposition's best midfielder.
He lost eight kilograms and rebuilt his endurance levels last pre-season and has remained in strong physical condition this summer through his individualised program.
