St Kilda forward Lance Collard is facing a potentially lengthy period on the sidelines after his alleged use of a homophobic slur in the club's VFL match on Friday.

According to reports on Saturday, Collard, 21, is alleged to have said a slur in the Saints' reserves' match against Frankston.

A swinging arm which caught a Dolphins player high late to a tackle attempt during play will also go to the MRO.

The physical incident sparked a response from the opposition in the middle of the ground with multiple players moving toward the scene.

The Saints released a statement on Saturday.

"St Kilda Football Club is aware of an alleged incident involving one of its players during last night's VFL match against Frankston," the Club said.

"The club takes matters of this nature extremely seriously and is working closely with the AFL Integrity Unit as it conducts its investigation into the matter.

"While this process is underway, it would be inappropriate for the club to comment further."

Collard was handed a six-game ban for repeated use of a homophobic slur during a VFL game in 2024.

"There is no excuse for using the language that Collard used on the weekend. Everyone understands it is totally unacceptable in any setting, ever," AFL General Counsel Stephen Meade said at the time.

"The AFL is very clear that homophobia has no place in our game, nor in society. We want everyone to feel safe playing in our game and Collard's behaviour does not help this.

Collard apologised for the incident, saying "I am incredibly remorseful for my comments and any hurt they may have caused".

"I'm disappointed in myself and fully accept the consequences for my behaviour," he said.

The VFL reportedly confirmed they are aware of an incident during the match.

Frankston claimed an eight-point win over St Kilda.
