Chris Hairston, Kenny Wiggins solidifying Chargers' offensive line

SAN DIEGO -- Chris Hairston was considered a swing tackle that could start a game in a pinch and give the San Diego Chargers serviceable snaps for an injured starter.

Kenny Wiggins didn’t even make San Diego’s 53-man roster at the end of training camp. But both Hairston and Wiggins have earned starting roles and helped keep Philip Rivers upright this season.

“It’s just gotten to the point right now where I look at Chris and Kenny as starters,” Chargers offensive coordinator Frank Reich said. “I think they’re legit starters, and we’re very fortunate to have them.

“Those guys have done themselves right. They’ve worked very hard and played the kind of football that warrants looking at them like that, and having the kind of confidence in them that we do.”

Hairston has five starts at left tackle, one at left guard and one at right guard this season. Wiggins was re-signed by the Chargers in Week 2, making four starts at left guard for an injured Orlando Franklin and one start last week at right guard for D.J. Fluker, who’s still suffering from concussion symptoms.

Hairston has played 513 snaps this season, while Wiggins checks in at 491. Only right tackle Joe Barksdale (734), center Trevor Robinson (618) and Fluker (597) have played more.

“Getting more reps in practice helps your confidence more,” Wiggins said. “So it’s just going out there and seeing the look. You can watch film as much as you want, but when you’re on the field getting the reps, it’s definitely a big help.”
