The Indianapolis Colts are expressing their support for Damar Hamlin and the Buffalo Bills.

Hamlin, a 24-year-old cornerback with the Bills, collapsed on the field during their Monday Night Football game against the Cincinnati Bengals.

The Colts tweeted support as did several individual Colts players. Hamlin made a tackle during the game at Paul Brown Stadium in Cincinnati when he got up from it and then collapsed.

The Bills said that Hamlin experienced a cardiac arrest on the field and he heart stopped.

He’s alive but critical at a Cincinnati hospital.
