Zimmer said he probably won't know until gametime, meaning the Vikings and the Tampa Bay Buccaneers could be in the dark about Bradford until gametime on Sunday (10 a.m. PT/1 p.m. ET, FOX, DirecTV). Keenum's completion percentage in Week 2 was the worst by a Vikings quarterback since Christian Ponder in Week 5 of the 2014 season.
Trae Waynes and Harrison Smith each picked off Jameis Winston in the end zone, and Andrew Sendejo returned an interception 36 yards in the fourth quarter to set up one of two field goals by Kai Forbath.
The 2017 Tampa Bay Buccaneers did an excellent job of maintaining their readiness to play in the immediate aftermath of Hurricane Irma.
The Vikings have six healthy scratches in receiver Rodney Adams, receiver Stacy Coley, defensive end Tashawn Bower, defensive tackle Jaleel Johnson, tackle Aviante Collins and guard Danny Isidora.
However, Tampa Bay had no answer for Keenum, who was also at the helm for the St. Louis/Los Angeles Rams for wins over the Buccaneers in 2015 and 2016.More news: Brexit: Boris Johnson could resign if Theresa May opts for 'soft Brexit'
And the Vikings' defense didn't look back after that. In a division this tough, every game matters and getting off to a good start to the season matters even more.
This week, this is a convenient truth, as there is only one game film to watch with Keenum running the Vikings offense.
The Bucs' offense came to life somewhat in the third quarter. Diggs started it with a diving 17-yard catch on the left sideline. He had a concussion and a sprained left shoulder that cost him two games with the Philadelphia Eagles in 2015. The Vikings turned that takeaway into a long touchdown drive and the game was never closer than a 14-point margin again.
Sam Bradford missed his second straight game with a knee injury, but Keenum was much better at home against a depleted Tampa Bay defense after a road loss at Pittsburgh last week.
Vikings Head Coach Mike Zimmer made it clear that Sam Bradford will be missing his second consecutive game on Sunday.
