Internet video has surfaced of Ray Lewis on the program Sport Science. (Hat tip to Shutdown Corner who posted this earlier today.)

Here's what the Sun's Ray Frager reported last month when the episode was originally broadcast: 

If Ray Lewis knocks at your door, better let him in. That's the lesson to be learned from the next edition of Sport Science (airing Sunday at 11 p.m. on Comcast SportsNet).

The program uses lots of high-tech equipment to film and measure actions of athletes in scientific fashion. In this case, Sport Science decided to compare the Ravens Pro Bowl linebacker with a battering ram. Each would be used to break down a thick, locked door.

Lewis filmed the show -- now in its second season -- in July in Los Angeles. He didn't get paid and stayed out on the field for six hours, said John Brenkus, creator and host of the series.

(The co-creator and co-executive producer is Mickey Stern, a Baltimore native.)

"It's literally a program that people do for free," he said. "By Season 2, everyone in the sports community had seen Sport Science. ... The sell just gets easier as the show goes on." 

I'll admit to not having seen the show before receiving a preview DVD, but, as my 12-year-old self would have said, it's pretty neat -- measurements of force, super slow motion from all angles.

But what about the risk of injury? (I checked with the Ravens, and a spokesman said the team had no idea Lewis did this.)

"The athletes are in such incredible shape, and we take every precaution," Brenkus said. "Where you get hurt is when you're not actually going full speed."
