The Texans terminated their qualifying offer to defensive lineman P.J. Hall, Aaron Wilson of the Houston Chronicle reports.
The team offered Hall an original-round tender worth $2.183 million on March 16.
The Raiders originally made Hall a second-round choice.
Las Vegas traded Hall to the Vikings last August, but Minnesota waived him with a failed physical. He signed with the Texans later that month.
Hall, 26, made 34 tackles and a sack in 10 games with Houston before going down with a torn pectoral.
In three NFL seasons, Hall has played 40 games with 27 starts. He has totaled 82 tackles, 10 tackles for loss, 2.5 sacks and nine quarterback hits.
