Houston brought Langford in for a workout on Tuesday and were impressed enough to sign him.
With DEs J.J. Watt and Whitney Mercilus going down with season-ending injuries, the Texans needed depth along their defensive line. In addition to Langford, the team also worked out DL Tyson Jackson and DL Lamarr Houston.
Langford, 31, is a former third-round pick of the Dolphins back in 2008. He spent four years in Miami and played three seasons for the Rams before signing a four-year, $17.2 million contract with the Colts back in 2015.
Langford was set to make base salaries of $4 million (2017) and $4.2 million (2018) over the remainder of the contract when the Colts released him with a failed physical back in August.
The Saints signed him to a contract and bounced on and off their practice squad. New Orleans decided to release him last week.
The Jets brought him in for a workout shortly after his release but did not sign him.
In 2016, Langford appeared in eight games for the Colts and recorded 10 tackles, no sacks, a fumble recovery and two pass defenses.
Houston, 30, is a former second-round pick of the Raiders back in 2010. After four years in Oakland, the Bears signed Houston to a five-year, $35 million contract that included $15 million guaranteed.
The Bears placed Houston on injured reserve during the preseason and recently released him with an injury settlement.
It is worth mentioning that Houston landed on the team’s injured reserve in 2014 and 2016 with ACL injuries.
Houston has worked out for the Saints, Patriots, and Buccaneers since being released but did not receive any offers.
In 2016, Houston recorded four tackles and no sacks for the Bears over the course of two games.
