Every week, Al Harris gets a little closer.

How close?

“Week 5,” the Packers cornerback says, leaning into the camera. “Let’s make it happen. The proof is coming soon.”

At the Atlantic Rehabilitation Center in Miami, Harris runs through a variety of drills emphasizing foot speed and agility as he continues his rehab from surgery on his left knee. In his exclusive video diary for the National Football Post, Harris short-hops over small hurdles, bounces on either side of a white line on his left leg and does short sprints outside.

He even offers well wishes to other NFL players working to come back from injuries – Brett Swain, Wes Welker and former teammate Aaron Kampman, who tore his left anterior cruciate ligament but signed a free-agent deal with the Jacksonville Jaguars earlier this month.

Harris knows how they feel.

“I know you guys are out there grinding,” Harris says, “so my prayers go out to you.”
