The Tennessee Titans have signed left tackle Taylor Lewan to a five-year, $80 million contract extension with $50 million in guaranteed money.

Lewan's deal is the richest for an offensive lineman in NFL history and makes him the highest paid OL in the league. His $16 million annual salary tops the $15.5 million per year of the fellow left tackle Nate Solder after the Giants gave him a four-year, $62 million deal earlier this offseason. Lewan on the fifth-year option of his rookie contract and will earn $9.3 million this season.

Lewan reported to training camp this week after sitting out the team's mandatory minicamp in search of a new contract. Titans GM Jon Robinson said earlier this week that talks with Lewan's reps were going well and that the two sides were “headed in the right direction” in terms of an extension.

Lewan sat out team drills during Thursday's practice as a precaution while his contract gets done. But now that he's signed, he can finally focus on training camp and prepare for the start of the season.

Lewan, 27, was the Titans' No. 11 overall pick in the 2014 NFL Draft and has emerged as one of the best left tackles in the league. He's played in 58 out of a possible 64 games over the last four years and has started all but one game since 2015. He's also made the Pro Bowl in each of the last two seasons.

With this historic contract, the Titans are betting on Lewan to be the long-term left tackle for franchise quarterback Marcus Mariota.
