MINNEAPOLIS — A brutal hit between two former Saints first-round draft picks knocked New England Patriots wide receiver Brandin Cooks out of Super Bowl LII in the second quarter. 

Cooks was ruled out for the rest of the game with a concussion. 

The fourth-year wide receiver, who the Saints traded in March for the Patriots' first-round pick and a swap of third-rounders, had just made the first Super Bowl catch of his career, a 23-yard pass from Tom Brady, and was circling around as he tried to find open field. 

Eagles safety Malcolm Jenkins, who won a Super Bowl as a rookie in New Orleans, leveled Cooks as the wide receiver turned, hitting him with the shoulder and connecting with his head in the process. 

Cooks appeared to be knocked out immediately. The Patriots wide receiver did not move after hitting the ground, and trainers came out quickly. 

Jenkins was not flagged for the hit. Cooks had already made the catch and established himself as runner, instead of a defenseless receiver, so Jenkins' contact was legal.
