In his first season with the Ravens, Houston led the team with 17 quarterback hits but was credited with only 4.5 sacks, his fewest ever for a full season and the second consecutive season in which his sack production has decreased.
Houston, who turned 33 in January, became the 39th player in NFL history to reach 100 career sacks. His 102 sacks is tied for the fourth most in the league since he entered the NFL in 2011.
His return helps to address the thinnest position on the Ravens defense.
There's uncertainty whether starting outside linebacker Tyus Bowser, who tore an Achilles in the season finale, will be ready for the start of the regular season. Outside linebacker Jaylon Ferguson died on June 21 from the combined effects of fentanyl and cocaine.

A 2011 third-round pick by the Chiefs, Houston has totaled 484 tackles, 165 quarterback hits, 18 forced fumbles, 17 fumble recoveries and 4 interceptions in 11 seasons for the Chiefs, Indianapolis Colts and Ravens.
