Liuget did not workout due to an undisclosed injury, running sprints while Chargers strength coach Kent Johnston looked on.
The Chargers are not required to disclose injuries by the NFL until Wednesday, when the first injury report is posted. Players have Tuesday off, and do not return to the field until Wednesday.
However, Liuget said he’ll be fine for Sunday’s opener against the Detroit Lions.
“I’ll be ready to go Wednesday,” Liuget said.
Attaochu missed five games his rookie season with a lingering hamstring injury, but he should be ready to play this week.
Offensive lineman Johnnie Troutman did not practice as he recovers from a broken right forearm. Troutman is projected to return in Week 3. And outside linebacker Tourek Williams also remains out with a fractured foot.
Players also voted on captains this week. Philip Rivers and Antonio Gates were voted captains on offense, while Eric Weddle and Liuget were voted captains on defense. Darrell Stuckey is the special teams captain.
