Goncalves (toe) has been ruled out ahead of Sunday's matchup against the Rams, Amanda Foster of the Colts' official site reports.
Goncalves didn't practice Wednesday or Thursday after likely sustaining a toe injury in Indianapolis' Week 3 win over the Titans, so it's no surprise he won't play Sunday. Dalton Tucker is expected to start at right guard in Goncalves' stead.
