Tigers forward Jack Riewoldt is in doubt to take on the Saints this Saturday after coughing up blood during the club's round nine loss to West Coast.

โ€œRight on the three quarter time siren, Jack Riewoldt bumped Liam Duggan as he was kicking,โ€ Sam McClure toldย SEN Afternoons.

โ€œHe came off second best from that bump. He was actually coughing up blood at three quarter time.

โ€œThat caused a little bit of an issue when they were coming home.

โ€œIt meant that they had to tell Virgin Airways staff the nature of Riewoldtโ€™s injury and then the club doctor had to have a few conversations with one of the pilots, the captain, of the flight coming home.

โ€œRiewoldt ended up flying home business class, he was eventually cleared to fly.

โ€œIt will put him in some doubt against the Saints on Saturday.โ€

The 29-year old was one of Richmond's best against the Eagles, booting five goals.

The Tigers meet the Saints on Saturday afternoon at the MCG.
