First reported by Michael Gehlken of U-T San Diego, I can confirm that Clary had offseason surgery to repair shoulder and hip issues that he dealt with last year.
No timetable was given on how long the injury will keep him out, so Clary's availability for the start of training camp at the end of July remains a question mark.
Clary, 30, did not play against Denver in the AFC divisional round due to a painful shoulder issue that he played through for most of 2013 season.
Clary had a clavicle injury that forced him to miss a game against Dallas on Sept. 29. Clary started 15 regular-season games for the Chargers, including three games at right tackle, and is part of an offensive line that returns all five starters from one of the top offenses in football last season.
The Kansas State product is in the final year of a contract that will pay him $4.55 million in total compensation for the upcoming season. Johnnie Troutman has been working at right guard with the first unit in OTA practices for the Chargers. Third-round selection Chris Watt has been working at right guard with the second unit.
Freeney's back: Not in attendance during San Diego's first OTA last week, veteran edge rusher Dwight Freeney was back on the field, although the Syracuse product was limited to working with the trainers on a side field.
Freeney still is recovering from surgery to repair a torn quad last October.
Williams gets a look: With Richard Marshall (undisclosed) and Jason Verrett (shoulder) not practicing, last year's fifth-round selection Steve Williams got some reps with the first-unit defense at cornerback, and looked like he belonged.
Williams made a nice deflection on a deep ball intended for Keenan Allen. The Cal product spent the entire 2013 season on the injured reserve after suffering a torn pectoral muscle in a preseason game against Chicago.
"He's healthy," safety Eric Weddle said. "He's always been an eye-opener for his speed and quickness. Mentally, he's got to stay with it and be totally confident in everything -- his checks, calls and technique. But he can play, and we're excited to have him back."
Davis making his mark: Undrafted rookie free agent cornerback Chris Davis continues to make plays when he's on the field. The Auburn product has been working at cornerback and nickel defender.
"Any time he's been in there with the 3s he's made plays," Weddle said. "He's batted balls down. He's explosive. So you like what you see from that point. But it's give and take. You don't want to put too much into it. You don't want to hype a kid up too much."
Weddle was asked if he knew Davis was the player who returned a missed field goal back 109 yards for the winning score in the Iron Bowl against Alabama.
"He's never said anything about it, so that's good," Weddle said. "If he came out and said something about it, then he'd probably drop lower on my totem pole. That's college. This is a much higher level than college football."
Rookies playing catch up: San Diego coach Mike McCoy once again reiterated it's up to the rookies to catch up with the veterans as far as learning the playbook and their assignments.
Those first-year players will have until the beginning of training camp to get acclimated, and then things really will start to speed up.
"We have a number of installations left in the next couple of weeks while were here," McCoy said. "We only have so many days out here, so we're throwing as much at them as we can. They're young players. They are going to make mistakes. The most important thing is they learn from it, and don't make the same mistake twice."
McCoy also said his team focused on the red zone on Monday, an area of the field his team struggled on offensively last season.
