Former Fremantle midfielder Anthony Morabito has retired after requiring more surgery on a troublesome knee.

He played four league matches for Claremont last year, joining the Tigers after being de-listed by the Dockers.

Fremantle drafted Morabito with the fourth pick in the 2009 national draft, with the hard-running midfielder playing 23 games in his first season.

However he could only manage another three senior games in the next six years as he underwent knee reconstructions in three consecutive seasons.

Morabito, 26, played 47 senior games at his original club Peel and last year’s four at Claremont before the knee issues curtailed his WAFL comeback.

Claremont defender Aaron Holt has also hung up the boots after failing to overcome a foot injury.

Holt played 68 matches, including the 2012 premiership.
