Vikings center Garrett Bradbury will miss a third consecutive game on Saturday against the Giants because of lower back spasms and tightness.
Bradbury has been ruled out after he missed practice this week. Two defenders are listed as questionable: linebacker Eric Kendricks (hip), who fully practiced Thursday, and cornerback Cameron Dantzler (ankle), who remained limited.
Center Austin Schlottmann will again replace Bradbury, who said he aggravated his back last weekend in a minor car accident near Eagan. Schlottmann is viewed by coaches as a "starting-caliber center in this league," said offensive coordinator Wes Phillips.
"Austin is about as steady as they come, as far as demeanor, intelligence, his mastery of the offense and the calls, all the things that the center has to do to communicate with everybody," Phillips said. "It's been a pretty seamless — we miss Garrett and want Garrett to get well as soon as possible — but everyone in this building has complete confidence in Austin."
A strong Giants interior defensive line of Dexter Lawrence and Leonard Williams awaits.
"They've definitely got some dudes up front," Schlottmann said. "They bring a lot of pressure, too. We have to be on our stuff with the protection calls."
Dantzler resurfaced on the injury report with a lingering ankle issue that limited him in practices Wednesday and Thursday. Cornerback Duke Shelley could get his third Vikings start on Saturday.
"We were able to see him move around and do some things," head coach Kevin O'Connell said of Dantzler. "We'll see how he turns over. He wasn't too sore [Thursday]."
