CHARLOTTE, N.C. — Carolina Panthers running back Christian McCaffrey isn’t giving up on this season despite being expected to miss four to six weeks with a right high ankle sprain, and he doesn’t want his teammates to give up because of an 0-2 start. “The last thing I want this team to focus on is the negative,” McCaffrey said less than 24 hours after suffering his first significant NFL injury during a 31-17 loss at Tampa Bay. “Football, especially in the NFL, can have a lot of factors that can affect your mental, emotional and physical play. “We’ve lost two games, not because we’re a bad team. That’s something that can be corrected, injury or not with me. This team has a lot of fight. Our team has a lot of resiliency. And we have the right guys to pick it up from here.” McCaffrey, 24, echoed what cornerback Donte Jackson said on Sunday about still having the potential to make the playoffs.
