Oakland Raiders guard Kelechi Osemele is inactive for Thursday's game against the Kansas City Chiefs with an undisclosed illness.
Osemele was listed as questionable on the team's injury report due to a knee injury but was widely expected to play.
The 27-year-old is a leading candidate for All-Pro consideration this year, fortifying the Raiders' offensive line.
Osemele signed a five-year, $60-million contract with the Raiders in March.
