Brown (shoulder) isn't practicing Sunday, Pete Sweeney of ArrowheadPride.com reports.
Kansas City head coach Andy Reid indicated that Brown is the only Chiefs player who will miss Sunday's practice session. The wideout's absence further supports the expectation that he'll miss the team's regular-season opener against Baltimore on Thursday. With that said, Kansas City elected not to place Brown on injured reserve to open the campaign, so there appears to be optimism that he'll be back in action by Week 4.
