Indianapolis Colts cornerback Darius Butler is "week to week" with a Grade 1 hamstring injury.
Grade 1 is the mildest kind of strain, but it still puts Butler's status in doubt for Week 3 against the San Diego Chargers.
The Colts' secondary is in shambles, having allowed 29.76 Net Expected Points on 72 passing attempts over the first two weeks of the season.
