After racking up nearly 90 yards from scrimmage in just over two quarters to start Sunday's matchup, star Minnesota Vikings running back Dalvin Cook suffered a groin injury on a third-quarter catch. 

He underwent an MRI on Monday, which Vikings coach Mike Zimmer said "went pretty well." Zimmer did follow up by saying, "We'll see how he does this week," but later reports were more encouraging, indicating that Cook avoided a major injury, though the team may exercise caution with a game against the 0-5 Falcons in Week 6 and their bye in Week 7. And it appears that's precisely what might happen, with indications now leaning toward Cook potentially sitting out against the Atlanta Falcons to enjoy two weeks of rest, per Adam Schefter of ESPN

With Cook being the centerpiece of the offense, the Vikings want to take no chances on his health.

The injury initially forced Cook to leave Sunday's game and undergo a locker-room evaluation, thrusting backup Alexander Mattison into the No. 1 running back spot for the Vikings, who deemed Cook questionable to return. The Pro Bowler did, in fact, return to the sideline -- and then onto the field -- later in the third quarter, but not for long. Mattison quickly resumed the full workload at running back, with Cook retreating to the sidelines after just one more play. Coach Mike Zimmer said afterward Cook couldn't play through the injury. If he has to miss time, it's assumed that Mattison will lead the backfield with Michael Boone filling in behind him.

A 1,000-yard breakout rusher in 2019, Cook entered Sunday night's affair as the NFL's leading ball-carrier through four weeks, with 424 yards and six touchdowns to his name. Fresh off a five-year, $63 million contract extension inked in September, he's been the centerpiece of Minnesota's offense for the last two years, scoring a career-high 13 touchdowns in 2019.

Injuries, however, are no stranger to the 25-year-old back. Cook missed 19 combined games between 2017 and 2019, including 12 as a rookie and five in his sophomore season. If he ends up missing more time in the Vikings' backfield, the team would figure to rely on Mattison, their 22-year-old former third-rounder, as well as reserve Mike Boone and veteran fullback C.J. Ham.
