Quarterback Mac Jones, already serving in relief duty for the injured Brock Purdy, told reporters after Sunday's 16-15 win over the Arizona Cardinals that he reaggravated the same PCL sprain that hampered him during training camp. "I had a little injury that I just re-aggravated," Jones told reporters. I took the brace off because I wasn't moving around very well, and then I put it back on after that. The interception came during Sunday's win, a mistake he owned up to:He had to do so on Sunday without key offensive playmakers like George Kittle, Jauan Jennings and Brandon Aiyuk, all out injured. I've had a lot of potential game-winning drives in my career, and a lot of quarterbacks have.
