Multiple league sources tell CBS Sports' Rob Rang that NFL teams will likely have to keep Florida State DE Tank Carradine (ACL surgery) from participating fully until training camp or later.Carradine tore the ACL in late November, so by training camp he'll be only eight months removed. Teams would be smart to play it safe with Carradine to avoid a re-tear of the knee ligament ala Ryan Broyles last year. Rang reports that Carradine's forty time at Saturday's Pro Day workout was actually 4.93, not the 4.75 reported by the Cincinnati Enquirer. Nevertheless, his recovery has been impressive. Carradine could be a steal if he falls to day two.
