"I had a couple of surgeries," Butler said. "I got those out of the way."
Butler refused to elaborate on the type of surgery he underwent. His season ended in Game 14 last season after he suffered a dislocated elbow.
"The reason why I played bad was, I just played bad," he said. "It happens."
"What I see is a guy who wants to get his game back in order," Nolan said. "Hopefully, he does it. He's said that he has a much better focus this year than he had last as far as his offseason goes. I'm very hopeful that he comes back in tip-top shape. We can start working on the things I hope to be able to teach him, to help him out and make him a better player."
Butler was expected to be a three-down linebacker for the Chargers last year. But as the 2014 season wore on, he was relegated to playing in the base defense.
Butler is entering his sixth season in the NFL after missing his entire rookie season due to injury. Over his career, the 26-year-old has 330 total tackles, 6.5 sacks, 12 passes defensed, three interceptions and four forced fumbles.
