Brown (knee) didn't practice Wednesday, Erik Bacharach of The Tennessean reports.
Brown, who's dealing with a bone bruise in his knee, sat out the Titans' Week 2 win over the Jaguars, and it's unclear if he'll be back in time to suit up this weekend against the Vikings. In Brown's absence last weekend, Corey Davis and Adam Humphries headed the Titans' wide receiver corps, while Cameron Batson and Kalif Raymond saw added work at the position.
