Carolina defensive tackle Kris Jenkins skipped a voluntary team workout, a month after the Panthers failed to trade the three-time Pro Bowl selection. Jenkins was one of only two players -- and the lone starter -- who missed the first day of three weeks of practices. While the sessions are voluntary, players usually attend. "Do we wish he was here? Sure," Panthers general manager Marty Hurney said. "It's a voluntary session and he chose not to be here. It's all we can do."
