Blake Baratz said Finley's decision to have surgery was made to help the player live a healthy life and be able to return to football.
"Regarding Jermichael's specific injury, it is important to note that expert opinions differ across the board, from surgical procedures to rehabilitation methods to returning to contact sports," Baratz said in a statement. "Working alongside the Packers organization, we have discussed and analyzed all of these opinions, as well as all of the potential scenarios moving forward.
"We have collectively determined that while surgery may not be 100 percent necessary, it is a proactive measure that should alleviate future risks with regards to a similar episode or re-injury."
Finley suffered a spinal contusion in his neck area, causing temporary numbness in his extremities, after a hit suffered during the Packers' 31-13 victory over the Cleveland Browns on Oct. 20.
The surgery will be conducted by Dr. Joseph Maroon, the Pittsburgh Steelers' team neurosurgeon.
