Melbourne's most successful jockey for the season Glen Boss will be back racing on Saturday after an enforced lay-off due to suspension.

Boss took the opportunity to undergo a planned operation on a stiff knee two-and-half weeks ago and on Monday was visiting the physio in preparation for his return to the track.

Boss has ridden 65 winners this season which leaves him well clear on top of the Melbourne jockey's premiership for the first time.

The 43-year-old Boss, who has never won any jockey title before in a career which started in country Queensland and moved to Brisbane, Sydney and then Melbourne, is 19 wins ahead of second placed Luke Nolen.

His biggest success this season came in the Cox Plate on Ocean Park.

The three-time Melbourne Cup winner on Makybe Diva, Boss has set a new record for a jockey for prize money earned on Victorian racetracks during a season with $9,334,285 so far in the 2012-13.

The previous mark of $9,215,040 was set by Damien Oliver in 2001-2002.

Boss, who resumes riding trackwork on Tuesday, is focusing almost entirely on Melbourne, declaring himself unavailable for interstate rides.

He has been confirmed for at least two rides in Saturday's Caulfield meeting.

He has the mounts on the Robbie Griffith-trained Nadeem Lass in the 1200m three-year-old fillies handicap and the Mick Kent-trained Harry Trimbole in race seven over 2000 metres.
