Sharrif Floyd said Thursday that he is starting at nose tackle on Sunday against Seattle as Linval Joseph recovers from a foot injury that forced him to miss practice on Wednesday and Thursday.
"It's my first start at nose," said Floyd, who normally starts at the Vikings' three-technique tackle spot. "But I'll be OK. I'm ready."
With Floyd at the nose, Tom Johnson will start at three-technique for the fourth time this season. The Vikings went 3-0 earlier this season with Johnson starting alongside Joseph while Floyd recovered from an ankle injury and surgery to remove loose cartilage in his knee.
"I don't think it's that big of a blow because there is no drop-off with our defensive line and how we play what we play," Floyd said. "We all understand what's going on. We all know the different techniques. We just have to play hard."
Seattle comes to TCF Bank Stadium ranked second in rushing attempts with 334. The Vikings are third with 331 carries, but the teams' running styles differ with Adrian Peterson healthy and Seattle's Marshawn Lynch sidelined because of hernia surgery.
"They run the ball a ton," Vikings coach Mike Zimmer said. "But it's not all hardball runs. They've got the zone read and the option and things like that."
Missing Joseph won't help. With 54 tackles, he is second in the league among defensive linemen behind Texans defensive end J.J. Watt (55).
