What concerns me about this news, being a physician, is the "sidelined indefinitely" portion of the news. This cervical disc bulge, as well as his symptoms, must be quite significant to warrant such a status. And what you fear is a repeated trauma to the neck to cause a full-blown disc hernation with nerve root compression to the point of intractable pain and loss of function. This sucks.
I think Blackburn will do a fine job aligning the D. Hopefully Goff and Sintin can pick up the slack.
