Brown (illness) was absent from the Texans' practice Thursday.
Brown -- who didn't catch a pass in Week 14 -- practiced Wednesday before popping up on the injury report Thursday as a non-participant, putting his availability for Sunday's game against the Jaguars in question. The 27-year-old led Houston's tight ends in snaps last week versus the Seahawks with 52, but if he can't go in Week 15, Antony Auclair and Brevin Jordan would likely both play larger roles at the position.
