The San Diego Chargers have claimed Zach Mettenberger off waivers.

Mettenberger was waived this week by the Tennessee Titans.

The Chargers held the No. 2 waiver wire priority behind the Cleveland Browns and reunite Mettenberger with Ken Whisenhunt.

Mettenberger offers prototypical pocket quarterback size, a big arm and a willingness to squeeze the ball into tight spaces. Mettenberger has a QBR of just 16.5 over the past two seasons.

Melvin Gordon underwent microfracture knee surgery this offseason in January.

Gordon had a disappointing rookie season with the San Diego Chargers.

Gordon's timetable for recovery is four to six months.

Gordon suffered the cartilage tear in his left knee that required surgery during a Dec. 20 game against the Dolphins.

"I'm getting better. I'm getting better," Gordon said. "I'm not where I want to be, but I think I'm ahead of schedule. I'm sprinting pretty well. I'm cutting."

Matt Slauson has signed a two-year deal with the San Diego Chargers.

Slauson was released by the Chicago Bears on May 1st.

Slauson made 12 starts at left guard last season and four at center.

The Chargers are expected to use Slauson at center, although the team added former USC center Max Tuerk in the third round of last week's draft.
