The Facts: Johnson says he's feeling explosive. If the rules were different, Johnson thinks he could've played in the Cardinals' playoff opener last weekend. But the veteran running back isn't eligible to come off short-term injured reserve until next week, meaning his Cardinals teammates need to win one more game Sunday at Carolina to give Johnson his chance in Super Bowl 50. "God-willing, we get there," Johnson said Tuesday, "and then, it's showtime."

Diehards Line: Johnson, 30, was among the NFL's leading rushers with 814 yards and three touchdowns on 196 carries in 11 games before landing on injured reserve with a tibial plateau fracture near one of his knees Dec. 1. Rookie David Johnson took over as the Cardinals' lead back and had a 187-yard game last month. But their run game has struggled the past few weeks - issues HC Bruce Arians attributed Monday to "getting our ass kicked up front." But if Arizona makes it to the Super Bowl, Johnson puts his chances for playing at 100 percent. "I'm playing," Johnson said. "I'm ready to go right now."
