The bye week came just in time for the undefeated Vikings (5-0).

Tight end MyCole Pruitt, who was only one of two available at his position for Sunday's win against the Texans, is set to undergo an MRI on Monday morning after leaving the game in the third quarter with a knee injury, according to head coach Mike Zimmer.

Zimmer said he doesn't believe it's the same knee Pruitt injured in the preseason. He sprained his medial collateral ligament Aug. 28 and did not play until the Vikings' win last week against the Giants.

Kyle Rudolph was the lone healthy tight end throughout the fourth quarter of the Vikings' 31-13 win.

Meanwhile, guard Brandon Fusco has entered the NFL concussion protocol after he was forced to leave the game during the first series. Fusco was injured while blocking Texans edge defender Jadeveon Clowney.

Zac Kerin filled in at right guard, meaning the Vikings played three opening-day reserves along the offensive line with two backup tackles, T.J. Clemmings and Jeremiah Sirles, already plugged into the lineup. While also thin at tight end, the Vikings used center Nick Easton as a sixth lineman for extra push on running downs.

Receiver Cordarrelle Patterson also briefly left the game with a hip injury before returning in the second half.

The Vikings' next game is Oct. 23 in Philadelphia.
