That's good news for Matthews and the team. After Matthews was injured during Friday's practice in a collision with rookie cornerback Jalen Mills, Pederson thought the injury was more serious.
"It looked bad on tape when I watched it," Pederson said Tuesday. "It looked worse than what I initially thought out here on the field. Now it's definitely day-to-day. There's no structure damage in there, which is definitely pleasing. On tape, it looks like it could have been."
Matthews could miss the first two weeks of preseason, Pederson said in the story. Chris Givens will start in Matthews' place Thursday in the team's preseason opener.
