The Minnesota Vikings, the NFL and University of Minnesota have consistently insisted that the turf at TCF Bank Stadium would be fine for Monday's game.
But after the Vikings practiced at the stadium for the first time Sunday, punter Chris Kluwe called the turf "unplayable" and called the NFL "hypocritical," given the emphasis on player safety.
"The field is as hard as concrete an hour and a half after they took the tarp off, and anyone that hits their head is getting a concussion," Kluwe said on his Twitter page. "I find it interesting that the NFL can claim an emphasis on player safety, and then tell us the field is fine. It's beyond hypocritical."
According to Kluwe, any player who hits his head on the turf is "getting a concussion," also noting that he hopes no one "gets catastrophically injured at the trainwreck that's about to take place tomorrow night."
Shortly thereafter, however, Kluwe said he was done addressing the field.
"I've been asked not to tweet anymore about the field so as not to distract teammates (who were there) and I will honor that," Kluwe wrote.
Kluwe's comments contrasted those of Vikings interim coach Leslie Frazier.
After the walk through, Frazier commended the condition of the field.
"A great job by the people that have worked on it all week long," Frazier told the team's website. "It really seems to me that there are going to be safe conditions. It's not something that our players have to be concerned about. We can just go out and play football, so it should be good for both teams."
