Cooks has suffered 5 known concussions in his NfL career, including two last season (within a 25 day period) and one the year before. He also left Super Bowl LII with a concussion while playing for the Patriots, making this his fourth in less than 3 years.
Normally, with this history, you would expect that he would be a very high risk for subsequent concussions. But his case is very unique. All of his concussions were grade I with his symptoms totally disappearing the day after the trauma. And his 2014 concussion was later deemed not to officially be a concussion at all......the Saints later admitted that they were being extra careful with their 1st round pick.
It is important to note, that in his NFL career, he has played 88 of 96 games..........and only 2 of his missed games were due to concussion (his 2nd last year within 25 days......therefore, extra precaution despite being mild).
Understand that while I cannot predict his future with exact numbers, it is concerning any time a player sustains a concussion, and he is likely some increased risk for low grade concussion in the future............ but a grade I properly treated leaves virtually no residual effects and little increased risk for subsequent major concussion.
