In one of his first shots as his teammate led 31-26, Cook was tackled at the bottom of the field and stripped of the ball. On the way down, Cook reached for the upper left side of his chest, seemingly aware of his injury. After a messy recovery, Cook remained on the pitch for several minutes while being looked after by the coaches.
Players and coaches from both teams surrounded Cook as he was helped to his feet and placed on a trolley. He was finally taken off the field with tears in his eyes.
The Vikings officially ruled out Cook for the rest of the match because of a shoulder injury.
Cook missed two games due to injury earlier this season, and was replaced in the squad by Alexander Mattison in those competitions. Mattison will likely replace Cook again if he has to quit at the end of the year. In two starts, Mattison made 51 times for 225 yards, 13 more catches for 99 yards and one touchdown.
