COSTA MESA, Calif. -- Offensive tackle Russell Okung struggled through a routine offseason workout for the Los Angeles Chargers on the final day of May. He couldn't explain why.
"It was during a normal two-minute drill -- something we do all the time in OTAs," Okung said. "I felt some shortness of breath and really couldn't get my bearings. And it sort of was lasting throughout the practice and throughout the day. And I said to myself, 'Man, I must be out of shape. Something must be off with me.'"
Okung was right: Something was wrong.
