Henderson (56) is comforted as he is carted off the field after an injury to his leg in the fourth quarter of an NFL football game against the Arizona Cardinals in Glendale, Ariz. When Henderson's femur snapped in Arizona in December, the gruesome injury caused many of his teammates to turn their heads. Now, improbably, E.J. is nearing a return to the field at training camp (AP Photo/Ross D. Franklin, File)
