The San Diego Chargers have reached an agreement with right tackle Joe Barksdale on Monday afternoon, locking him in until 2020, as announced on the team’s twitter account.

All of the details of the contract are not available yet, but it is confirmed to be a four-year deal.

Barksdale, coming into his sixth NFL season, was the only Chargers offensive lineman to start all 16 games in the 2015 season, and was named Lineman of the Year for the Chargers.

Additionally, he was not called for a holding penalty in the entirety of the 2015 season.

Barksdale was one of the few bright spots in a taxing season for the Chargers.

The Louisiana State University was drafted by the Oakland Raiders with the 92nd overall pick in the 2011 NFL draft, but lasted only a year before he was released.

He spent the next three season with the St. Louis Rams, starting in 15 games from 2012 – 2014, until he signed a deal one-year deal with the Chargers.

He joins the likes of tackles D.J. Fluker and King Dunlap and guard Orlando Franklin, all of whom also received four-or-five-year contracts in the past year.
