"I was just upset that I'm getting cut 11 years in (the NFL) from a guy who I don't even know," Williams said, per The Star Tribune. "I figure between the pain and the fact he cut me when I wasn't looking was my reaction."
UPDATE: Frazier announced Monday in a team statement that Williams hyperextended his right knee against the 49ers.
"An MRI exam today revealed a significant bone contusion as well as a posterior capsular strain," Frazier said. "Kevin was fortunate in that there was no injury to any of his ligaments."
