HOUSTON — The Houston Texans have hired Brian Gaine as general manager and extended the contract of coach Bill O'Brien through 2022.

The team announced the deals Saturday. Gaine signed a five-year contract and O'Brien was extended for four years.

Gaine brings 19 years of NFL personnel experience to Houston. He spent the 2017 season as the Buffalo Bills' vice-president of player personnel. He also served as the Texans' director of player personnel from 2015-16 and director of pro personnel in 2014.

Texans owner Bob McNair calls Gaine an "incredibly smart, hardworking individual that understands the importance of good communication."

Houston finished 4-12 this season after consecutive AFC South titles the previous two years. O'Brien's 31 career victories in four years are tied for the most by a coach in franchise history.
