Several points in this post are erroneous.
Herniation is rupture of the outer fibrous ring (annulus fibrosus) which then causes extrusion of the inner gelatinous material (nucleus pulposus).
Rupture and herniation are identical, and this is not caused by swelling, but by degeneration or trauma.
Herniation certainly distorts the anatomy locally, but there is not necessarily nerve root entrapment. The gelatinous material eventually reabsorbs, and discomfort from that pressure resolves. Steroids and non-steroidal anti-inflammatory medication help to resolve the swelling and subsequent pressure, but do not bring about healing. Steroid injections are likely to reduce swelling and pressure rapidly - within hours to days, and local anesthetic injections are effective immediately.
The serious consequence of of a tear (or herniation) of the outer fibrous ring is displacement of the fibrous material in such a way to cause direct entrapment of a spinal nerve, which results in significant pain and and dysfunction along the entire path of the nerve. If there are no radiating neurological symptoms, then there is no nerve entrapment, and the injury is not serious and requires no surgery. Furthermore, even passive range of motion may displace a fibrous component which is compressing a nerve, causing the nerve to then be decompressed and relieving the neuropathy.
An MRI shows the details of this anatomy, and no further testing is needed if there are no significant distal nerve symptoms (radiculopathy).
So, it is feasible that such an injury may NOT require surgery or even be very limiting within a few days of its occurrence. You or your quarterback may be able to carefully go back to work.
