Suspended AFL footballer Andrew Lovett has lodged a notice of grievance with his new club St Kilda.

The Saints suspended Lovett indefinitely on Christmas eve after a woman made a complaint to the police about an alleged sexual assault.

Lovett is currently under police investigation and his AFL future is in jeopardy.

Lovett's manager Alex McDonald, the AFL and the Saints all declined to comment on the notice on Tuesday.

It is unclear when the police will finalise their investigation.

Lovett, 27, played 88 games for Essendon from 2005 but a succession of off-field incidents marred his time with the Bombers.

He was traded to the Saints at the end of last season in exchange for their first-round draft pick at No.16.

The Saints signed him on a three-year deal, hoping his explosive speed would give their midfield a crucial boost as they try to improve on last year's grand final loss to Geelong.

But Lovett made a disastrous start at his new club when he was arrested for drunkenness on November 14, although the charge was dropped.

The Saints suspended him within hours of becoming aware of the women's allegation.

The club will not comment about Lovett's future until the police conclude their investigation.
