News of the trade was first reported by The Athletic.
Conley, who was Oakland’s first-round pick (24th overall) in 2017, has one interception this season in six starts.
The Texans have been aggressive on the trade market this season. Before the season, Houston acquired left tackle Laremy Tunsil and wide receiver Kenny Stills from the Miami Dolphins for two first-round picks, traded linebacker Jadeveon Clowney to the Seattle Seahawks for a third-round pick and two players and acquired running backs Duke Johnson and Carlos Hyde in separate trades with the Cleveland Browns and Kansas City Chiefs, respectively.
Conley has four interceptions, 18 passes defensed and 67 tackles in 23 career games.
In Week 1 against the Broncos, Conley suffered a neck injury and was strapped to a gurney and taken off the field on a cart when he tried to take down Denver running back Royce Freeman on Monday Night Football. Conley, though, played for Oakland the following week.
The 24-year-old starred at Ohio State. Two days before the NFL draft, he was accused of sexual assault, but he did not face discipline from the NFL because it happened before he was officially in the league.
