The Texans signed former Rams cornerback Kayvon Webster and waived nose tackle Marcus Hardison on Monday.

Heading into their final preseason week, the Texans continue to fortify their secondary, which saw the additions of Tyrann Mathieu, Aaron Colvin and Johnson Bademosi in free agency.

"I think it's getting close to being official, but we have some guys on the staff with some history with him and things like that," head coach Bill O'Brien said earlier Monday. "Looking forward to getting him here and seeing how it goes."

Webster (5-11, 190) spent four seasons with the Denver Broncos (2013-16) and played along Texans assistant coach Wes Welker for two of those seasons (2013-14). Senior director of sports performance Luke Richesson, who oversaw the Broncos strength and conditioning program from 2012-17, also worked with Webster. General manager Brian Gaine served as the assistant general manager for the Miami Dolphins during Webster's collegiate career (2009-12) at South Florida.

The Texans faced the six-year veteran last season during his stint with the Los Angeles Rams.

Webster (5-11, 190) started 11 games for the Rams, recording 38 tackles, including 34 solo, seven passes defensed and one interception before suffering a season-ending Achilles injury.

Webster was not on the field for Houston's preseason game in L.A. this past weekend, as he is still working his way back from injury.

Off the field, Webster founded his own trucking business, Webster Express Inc. based out of Miami. In March, he started Vybe305, a food truck in Miami and Los Angeles. In 2015, Webster also helped start Tru Prep Academy, an all-male private school located in Miami Gardens, Fla. serving students in grades 4-12.

Webster will wear No. 36 for the Texans.
