NFL Week 12 - The Los Angeles Rams have officially ruled out quarterback Matthew Stafford for Sunday's game against the Kansas City Chiefs, according to NFL Network's Ian Rapoport. Further reporting from ESPN's Adam Schefter specifies Stafford's injury has been labeled a strained neck.
Stafford missed time in Week 10 after entering the league's concussion protocol. He was replaced by John Wolford, who then exited late in the fourth quarter with what was later diagnosed as a "stiff neck," per CBS Sports. Stafford was able to play Week 11 against the New Orleans Saints.
