Houston led 16-6 at halftime but lost 34-30 to Dallas after CeeDee Lamb's 12-yard touchdown catch with 40 seconds left capped a career day (17 catches, 189 yards); it is Houston's first 0-4 start since 2020, and coach DeMeco Ryans said the defense failed to close it out.

Coach DeMeco Ryans said he expects to open 21-day practice windows this week for WR Tank Dell, T Braden Smith and DT Kayden McDonald, with their availability for Sunday at Tennessee contingent on how they respond in practice.

Dallas scored on 4 of 5 second-half possessions; Houston's C.J. Stroud threw for 347 yards and an 87-yard go-ahead drive that ran out of time. LB Azeez Al-Shaair (groin) and S M.J. Stewart (knee) were out.

CeeDee Lamb's late touchdown catch won it for Dallas; Houston got a bright spot in Nico Collins' return from injury (7 catches, 118 yards, 2 TDs) but couldn't hold a second-half lead.

The move adds linebacker depth as Houston searches for answers during its winless start to the season.

Houston will be without OLB Azeez Al-Shaair and S M.J. Stewart as the winless Texans host Dallas.

Ryans took personal responsibility for the slow start and urged the locker room to block out outside noise.

Houston managed only 223 total yards in the loss that produced its current last-place standing in the AFC South.

Winless Houston (0-3) placed running back British Brooks on injured reserve, further thinning an already depleted backfield ahead of Sunday's game against Dallas.

Houston (0-3) marks its 25th anniversary season with a halftime alumni ceremony as it hosts Dallas; QB C.J. Stroud ranks 7th in the NFL in passing yards with zero interceptions this season.

Houston's top receiver, who missed two games, is back for a rematch with Porter, who held him to three catches and a concussion in last season's playoff loss.
