Raiders MLB Rolando McClain underwent stem-cell therapy to address chronic pain in his knee and ankle this offseason.
"I've been having two seasons of nagging pain in my knee," conceded McClain, who says he now "feels a lot better." A radiologist in Gulf Shores injected fat cells from other parts of McClain's body into the knee and the area of a previous high ankle sprain. McClain is now working out five days per week, and says he's able to sprint "with hardly any pain at all."
