Rockies' Arenado leaves game vs. Cardinals with chest contusion; considered day-to-day

The injury-ravaged Colorado Rockies can add their Gold Glove third baseman to their long list of casualties.

Arenado was replaced in the fourth inning by Rafael Ynoa and it's unclear exactly how he suffered the injury.

The team is already missing talented All-Stars Justin Morneau (ribs), Carlos Gonzalez (knee) and Troy Tulowitzki (hip flexor) to injuries.

The team should provide an update on his status following the game.
