The move comes as no surprise, since Watt confirmed Sunday night he would miss the rest of the season with an injury sustained in the Texans 27-24 win against the Oakland Raiders.
Watt torn his pectoral muscle, ending his season for the third time in the last four years.
He is expected to recover in time to return for offseason activities.
The Texans defense is dealing with an outbreak of injuries, specifically in the secondary.
Starting cornerbacks Bradley Roby and Johnathan Joseph have been sidelined with hamstring injuries. Rookie cornerback Lonnie Johnson Jr. is in the concussion protocol and safety Tashaun Gipson Sr. has been limited with lingering hip and wrist injuries.
He has played in 43 career regular season games (21 starts) over three seasons with the Cleveland Browns (2016-18), recording 128 total tackles (103 solo), 19 passes defensed, three interceptions, five quarterback hits, two tackles for loss, 1.0 sack, one forced fumble, 10 total special teams tackles and one interception returned for a touchdown.
