Ulrich spent two seasons with the team, making 10 appearances on the offensive line for the Colts.
"I am heartbroken to hear of the passing of Matt Ulrich," Irsay said in a statement on social media. "Matt was with us only two seasons but left his mark on many. Great guy, I hear he was a great dad — and he was a Super Bowl champ. My prayers to his family."
Ulrich played football at Northwestern University before signing with the Colts as a rookie in 2005.
He was a member of the Super Bowl XLI-winning Colts team.
