A hamstring injury caused Cook to miss four consecutive games from Weeks 5-8. But the second-year pro returned against the Detroit Lions and quickly put aside any concerns over his health with an explosive 70-yard run in the second quarter.
"I'm ready to go," Cook said. "I'm fired up. It's a big week, man, and for me to be healthy and out there, I'm just happy ... We're going to see if I'm 100 percent, but with my body, I feel great. So yeah, I'm there."
The Vikings could certainly use a backfield at full strength when considering the opponent, and Sunday won't be easy even with a fully healthy Cook.
The Bears enter Week 11 ranked fourth in total defense, allowing 319.6 yards per game, and boast the second-best run defense in the league (84 yards allowed per game). Chicago's run defense has also allowed a league-low two rushing touchdowns on the season.
