After straining ligaments in his ankle, the 24-year-old went under the knife on January 21 and it was thought he would miss at least three months.
The Bombers are still planning for his return around Anzac Day in late April but have admitted he's tracking a fortnight ahead of planned and he is no longer in a moon boot.
"I saw him last night and he said he spoke to the surgeon and he's actually two weeks ahead of schedule," assistant coach Matthew Egan told SEN on Wednesday morning.
"He was walking around in normal shoes last night and a week ago he was in a moon boot.
"He's progressing really well.
"He's a really important part of our forward line last year … he just gives really big contests and it allows Joe Daniher to get a smaller opponent too, which will help him."
Bellchambers kicked 28 goals last year - the second most at the club - across the 18 games that he played.
Paddy Ryder is the only other senior listed ruckman at Essendon. Daniher is in his second season and rookie Fraser Thurlow will need promotion to play senior football.
