Tommy Kelly, who was Oakland’s starting right defensive end for the first four games, started at tackle against San Diego last week and made two tackles. The 6-foot-6, 300-pounder leads all Raider defensive linemen with 18 tackles. He also has one sack this season.
Gerard Warren has not practiced since the bye week when he suffered a thigh injury. The team leader in sacks with three, the veteran defensive tackle was hopeful of returning against the Chiefs but was declared out on Friday.
With Kelly being moved inside, the Raiders will use rookie Jay Richardson at defensive end. Chris Clemons will also see time on passing downs.
The good news for Oakland is that defensive tackle Warren Sapp is listed as probable to play against Kansas City. Sapp did not practice either Wednesday or Thursday due to a sore ankle but the team expects him to be available on Sunday.
Linebacker Sam Williams, however, isn’t likely to play. Williams has a shoulder injury and was limited in practice.
Veteran Robert Thomas, who started and made a team-high eight tackles against San Diego, will likely get the start against Kansas City.
