Playing in Kurt Warner's annual flag football tourney Saturday, David Johnson didn't have to do much -- the players involved are the all-time quarterbacks for their teams, which basically means grabbing the ball and standing there until someone gets open.

(Although I saw a first in all my years at this event, which started in 2004. Falcons wideout Mohamed Sanu -- pictured below, laughing with Johnson -- actually played defense for his team a couple of times.)

Johnson has some work to do as a quarterback. But as for his day job -- and the knee injury he suffered late in the season -- all is better now.

"My wheel is good," Johnson said. "Good to go already. Back training, full throttle. Doing everything."

He admitted he got a "harsh reminder" not to do things like jump out of pools, which he had put up on social media while rehabbing.

"I just wanted to show people I was back and ready to go," Johnson said. Back to 100 percent? "For sure," he said.
