Don’t expect Cardinals running back David Johnson to be back on the field just yet. The veteran, who has been dealing with ankle and back injuries in recent weeks, likely will be out against the 49ers for Thursday’s matchup, according to ESPN, which cited unidentified sources. He is officially listed as questionable after being limited in practice Wednesday.

Even with the quick turnaround, Drake said he’s ready to make an immediate impact.”I’ve always been the type of person, you go to a swimming pool, you don’t just dip your toe in, you dive right in,” Drake said Wednesday (via the team’s official website). “This is up my alley.”It really started to click when I got on the field because I’m more of a tactile learner. I’ve got to go out there and run around and get the plays from there. The more I’m on the field, the more comfortable I get … The bullets are flying, and I’ll be ready.” When asked about Johnson’s chances of playing Thursday, Arizona coach Kliff Kingsbury was reserved about giving more details. He explained Johnson is “working through it” and said the Cardinals would use a “running back by committee” approach against San Francisco as backup Chase Edmonds has been ruled out with a hamstring injury. Johnson, who has rushed for 300 yards and two touchdowns in seven starts, also missed the team’s 31-9 loss to the Saints on the road last Sunday. He has been considered a game-time decision against the undefeated 49ers.
