Sources: Titans, center Ben Jones agree to 4-year contract

HOUSTON -- Texans center Ben Jones has reached an agreement in principle to sign with the Tennessee Titans on a four-year deal, sources told ESPN. Jones' deal cannot become official until 4 p.m. ET on Wednesday.

Jones was a fourth-round draft pick in 2012. He became the Texans' starting center in 2015 after Houston released long-time center Chris Myers. Jones helped the team weather a season in which they started four quarterbacks. Before 2015, Jones started every game in 2014 at left guard and played guard in both of his first two seasons as well.

The Texans are also negotiating with right guard Brandon Brooks, who is set to become a free agent on Wednesday.

The Titans have many questions on their offensive line, notably at left guard and center.

Jeremiah Poutasi, a third-round pick in 2014, started off at right tackle but moved to guard when Mike Mularkey became the team's head coach, and Poutasi didn't start down the stretch. Undrafted rookie Quinton Spain was ahead of him on the depth chart.

Center Brian Schwenke missed time with a leg injury, which caused the Titans to turn to rookie Andy Gallik.
