Brown (hamstring) doesn't carry an injury designation and will be available for Sunday's game against the Colts, according to Turron Davenport of ESPN.com.
Brown was dealing with a hamstring injury, but he logged a limited practice Thursday and was a full participant Friday, so he should be good to go for Sunday against the Colts. He recorded seven tackles (five solo) in Week 1 but was inactive last weekend against the Seahawks.
