Brown (knee) ran routes during practice Monday, Jim Wyatt of the Titans' official site reports.
Brown has been sidelined for most of the team's offseason activities after undergoing surgery on both of his knees. He briefly practiced during training camp, but a reported flare-up in his knee partway through August has kept him sidelined since. Brown did not participate in any preseason action, which makes his participation in practice a bit more notable. The team has consistently stated that Brown will be ready for Week 1 of the regular season against Arizona, and his activity at practice backs that notion.
