Brown (knee) wasn't spotted during the early portion of Friday's practice, Erik Bacharach of The Tennessean reports.

A bone bruise in his knee has Brown looking iffy for Sunday's game against the Jaguars, and he could be ruled out for Week 2 action as soon as Friday afternoon. If he's inactive or limited this weekend, added targets would be available for both Corey Davis (hamstring) and Adam Humphries, with Kalif Raymond and Nick Westbrook-Ikhine also in the mix.
