Denver Broncos quarterback Peyton Manning will undergo a routine end-of-season neck examination later today, according to CBS Sports.
The 37-year-old has already passed his end-of-year physical, but will now have his annual neck check-up as the Broncos wrap up their season.
Manning's contract states that he must have a neck exam at the end of every campaign.
The 2013 NFL MVP has no intention of retiring - and hopes to play a starring role for the Broncos throughout the 2014 campaign.
His playing career, however, will be in jeopardy if doctors decide that he should consider calling it a day.
Manning is due to be paid $20m in 2014, but that could be voided if he suffers a neck injury during the next season.
The former Indianapolis Colts star, though, is expected to receive the green light from doctors.
