Thursday's Chiefs practice report

KANSAS CITY, Mo. -- Outside linebacker Justin Houston returned to Kansas City Chiefs practice on a limited basis but has yet to be cleared to play in Sunday's game against the Oakland Raiders at Arrowhead Stadium.

Houston was hit in the head/neck area last week against the Tennessee Titans. He remained in the game. He did not practice Wednesday.

The loss of Houston would be a major one for the Chiefs. Houston leads the Chiefs with 8.5 sacks.

If he doesn't play, Houston would be replaced by veteran Frank Zombo, a former starter with the Packers. Zombo had four sacks as a rookie in 2010.

Running back Jamaal Charles, who has blisters on his feet, also returned to practice on a limited basis after sitting out a day earlier.

Two starters, tight end Anthony Fasano (knee/ankle) and free safety Kendrick Lewis (ankle) did not practice. Backup tight end Travis Kelce (knee) did not practice and will not play against Oakland.

Other players listed as practicing on a limited basis were wide receiver Donnie Avery (shoulder) and punter Dustin Colquitt (knee).

Listed as full practice participants: tackle Eric Fisher (concussion), guard Jeff Allen (groin), tight end Sean McGrath (knee), fullback Anthony Sherman (knee), offensive lineman Geoff Schwartz (tricep) and linebacker Dezman Moses (toe).
