Morning links: Clary's second hip surgery

Good morning. Michael Gehlken of U-T San Diego reports that San Diego Chargers offensive lineman Jeromey Clary had a second surgery on his ailing hip, and could miss the entire 2014 season.

Clary had offseason shoulder and hip surgery, and was placed on the reserve physically unable to perform (PUP) list, meaning he will miss at least the first six weeks of the season. Clary also took a pay cut. Scheduled to make $4.55 million in 2014, Clary will now make $1.6 million in guaranteed salary.

The Chargers carried five running backs, but just eight offensive linemen on the 53-man roster, so depth could be an issue down the road if Clary can’t get back on the field. San Diego has four linemen who can play guard in Johnnie Troutman, Chad Rinehart, Chris Watt and Rich Ohrnberger.

They also have another option at guard in Craig Watts on the practice squad. And Kenny Wiggins, released during roster cuts, remains available on the open market.

According to Jimmy Kempski of Phlly.com, the Chargers have the fifth-oldest team in the NFL, with an average age of 26.64.

Trey Cunningham of Pro Football Focus offers five reasons to be confident and five reasons to be concerned for the Chargers this upcoming season.

Tom Krasovic of U-T San Diego wonders if this is the final season for Ryan Mathews with the Chargers, as this team was built to be less dependent on his services.

Paola Boivin of the Arizona Republic notes that Cardinals starting running back Andre Ellington averaged 5.5 yards per carry his rookie season. Run defense was an issue for the Chargers during preseason play.
