Brown (illness) didn't practice Wednesday, Jim Wyatt of the Titans' official site reports.
Brown was added to the Titans' injury report this past Sunday after experiencing a case of food poisoning, but he was able to suit up in Monday's 34-31 win over the Bills. He logged 42 of a possible 53 offensive snaps in the victory, finishing with seven receptions for 91 yards. His availability for this weekend's game against Kansas City doesn't appear to be in any danger, but the same can't be said for fellow starting wideout Julio Jones (hamstring), who didn't finish Monday's contest and was unable to practice Wednesday.
