In his first two years in the league, Raiders linebacker Rolando McClain has been solid, accumulating a total of 184 tackles, 5.5 sacks and an interception. But for a guy who was taken No. 9 overall in the 2010 draft, it’s fair to say Oakland’s front office might have expected a little more from McClain.

The Mobile Press Register, though, presents to us perhaps one reason why McClain hasn’t become a superstar. Possibly it's because the nagging pain in his knees have been killing him the past two years (not literally, of course), and the high ankle sprain he suffered last season didn’t help either.

That’s why McClain has turned to stem cell therapy this offseason in an attempt to make his legs as healthy as possible. The procedure was straight-forward. A radiologist out of Gulf Shores, Ala., liposuctioned fat cells from McClain and then injected those cells into his knee and ankle.

Now, McClain is working out four days a week with the Raiders, and he’s hardly having any pain at all.

“It,” McClain told the Mobile paper, “feels a lot better.”

“This is going to be the future of medicine,” said Jason R. Williams, the radiologist who performed the procedure on McClain.

As we’ve detailed before, Broncos quarterback Peyton Manning, when he was still in Indianapolis, flew to Europe to undergo stem cell therapy on his neck and unemployed receiver/actor/TMZ star Terrell Owens traveled to Korea last year for the same kind of therapy on his knee.

And while McClain is scheduled for a May 17 trial for allegedly threatening to kill a man and firing a gun near his ear last November, here’s hoping his stem cell therapy makes him as happy as this guy.
