St Kilda midfielder David Armitage will sit out the remainder of the 2017 season following two groin operations that has limited his output this year.

The 29-year-old appeared in the Saints' round one and four sides before undergoing surgery.

He returned through the VFL in July in a bid to return to senior football however senior coach Alan Richardson admitted the club had pushed the veteran's recovery in a bid for him to play senior football again in 2017.

โ€œUnfortunately for Dave heโ€™s been fighting the clock to try and get himself healthy at the back end of the season,โ€ St Kilda's General Manager of Football Performance Jamie Cox toldย saints.com.auย on Tuesday afternoon.

โ€œHe looks to have lost that battle as well and is his season looks like it might be done.โ€

The club expects the Armitage to be fit for the start of pre-season.

In more positive news, the club is very confident that Nick Riewoldt will be fit for Sunday's crunch clash against Melbourne at the MCG.

Riewoldt suffered a concussion following a contest with West Coast's Dom Sheed on the weekend.
