Panthers signed WR Tiquan Underwood, formerly of the Bucs, to a two-year contract. Underwood and Jerricho Cotchery now sit atop the Carolina depth chart at receiver. Underwood, 27, had a career-year last season, catching 24 passes for 440 yards and four touchdowns. He started seven games opposite Vincent Jackson while Mike Williams was sidelined. Underwood owns a career 16.0 YPR mark and will provide a sneaky deep threat for Cam Newton.
