Chargers add right tackle Joe Barksdale to mix at offensive line

The San Diego Chargers on Tuesday continued to add depth up front at offensive line.

Joe Barksdale has agreed to terms with the San Diego Chargers on a one-year deal, the team announced.

Financial terms of the deal were not disclosed.

Barksdale, 27, started 29 games at right tackle for the St. Louis Rams over the past two seasons. However, St. Louis selected Wisconsin tackle Rob Havenstein in the second round of this year's draft, allowing the Rams to move on from Barksdale in free agency.

Barksdale visited the Atlanta Falcons, Tennessee Titans and Chargers.

The Chargers have mulled the possibility of moving right tackle D.J. Fluker inside to guard this offseason after an uneven performance in 2014. San Diego signed tackle Chris Hairston to serve as the team's swing tackle in April.

However, Fluker reportedly lost weight and is healthy, so it will be interesting to see whether he will be given the opportunity to compete for the starting right tackle job, or asked to move inside to right guard, replacing Johnnie Troutman as the team's starter there.

General manager Tom Telesco has repeatedly said that Fluker will remain at right tackle this offseason.

The Rams originally added Barksdale off waivers from the Oakland Raiders on Sept. 27, 2012. After serving in a backup role most of that season, Barksdale became more prominent for the Rams in 2013 when he started 13 games at right tackle.

Barksdale stayed at that spot last year, starting all 16 games at right tackle.

He entered the league as a third-round pick for Oakland in the 2011 NFL draft.
