The Texans are working out former Miami Dolphins cornerback Tony Lippett on Monday night, according to league sources not authorized to speak publicly.
Lippett is a big corner at 6-3, 200 pounds and a former fifth-round draft pick from Michigan State.
Lippett has 80 career tackles and four interceptions.
The former track sprinter and All-Big Ten football selection was cut by the Dolphin in September.
Lippett tore his Achilles last year and spent the entire season on injured reserve.
