Cardinals' Johnson back to full health after rehabbing knee

Arizona Cardinals running back David Johnson revealed Saturday he's back to full health after rehabbing his knee during the offseason.

Johnson sprained his MCL during the regular-season finale against the Los Angeles Rams, putting a damper on a prolific campaign in which he notched 20 total touchdowns.

"My wheel is good," Johnson said via Darren Urban of the Cardinals' official website. "Good to go already. Back training, full throttle. Doing everything."

Johnson participated in Kurt Warner's flag football tournament and showed no signs of wear.

The standout running back rushed for 1,239 yards and 16 touchdowns, adding 80 receptions for 879 yards and four more scores.
