Forgot this is not his first. The advice of most surgeons, not just the very careful Packer's approach, is that two fusions are too great a risk with limited flexibility to continue to play football.

The injury could spell the end of Richardson's career because it is a similar injury to the one he suffered in 2012 and required fusion surgery of the C-5 and C-6 vertebrae.

According to neurosurgeons who have performed fusion surgery, a second herniation typically occurs directly below or above where the fusion took place. Richardson's latest herniation took place below the fusion, the source said.

Richardson was added to the injury report Thursday with a neck injury and was listed as a limited participant. He practiced in full on Wednesday, but was experiencing neck pain the following day and an MRI was ordered.
