Brown didn't practice Wednesday due to a hamstring injury, Aaron Wilson of ProFootballNetwork.com reports.
Wilson relays that the team doesn't consider the injury a long-term issue, but it's possible the Texans play it safe and sideline their primary backup tight end for Friday's preseason game against the Rams. Brown caught 23 passes for 171 yards across 572 offensive snaps last year, but he lost 18 pounds this offseason and is looking to breakout in his third season with Houston.
