Moeaki in for Chiefs; Flowers still out

The AFC West-leading Kansas City Chiefs, 6-4, got good and bad news Thursday on the injury front as they prepare to play Sunday in Seattle.

Standout rookie tight end Tony Moeaki returned to full participation in practice Thursday after dealing with a head injury that kept him out of the Chiefs’ win against the Cardinals on Sunday. If he doesn’t have a setback, he should play at Seattle. It also looks like fellow rookie, receiver/running back/returner Dexter McCluster is on track to play Sunday. He practiced fully for the second straight day Thursday after missing four games with an ankle injury.

However, cornerback Brandon Flowers, who is having an outstanding season, didn’t practice again Thursday because of a hamstring injury he suffered against Arizona. It might be difficult for him to play Sunday. Guard Ryan Lilja (foot) and tackle Branden Albert (groin) continued to be limited in practice Thursday.

In Oakland, Raiders’ coach Tom Cable said star left cornerback Nnamdi Asomugha is “90 percent” and remains on track to play Sunday against Miami, as expected. He's missed two games with an ankle injury.

Denver linebacker D.J. Williams was limited in practice for the second straight day with a concussion suffered Monday night in San Diego. The team is hopeful he'll play against St. Louis. Linebacker Robert Ayers looks to be on track to play against St. Louis. He practiced fully Thursday for the second straight day after missing several weeks with a foot injury.

Some players in Pittsburgh are not pleased that Oakland defensive lineman Richard Seymour didn’t get fined heavier for knocking down Steelers quarterback Ben Roethlisberger on Sunday. Seymour was fined $25,000. It is not being received well in Tennessee, either.

Former Denver assistant Mike Heimerdinger is going to finish his work week, remarkably, before starting treatment for cancer next week. He is the offensive coordinator in Tennessee.

It was a tough day for former Denver cornerback Alphonso Smith in Detroit’s 21-point loss to New England on Thursday. Smith gave up three touchdowns and was benched in the Lions’ loss. He has five interceptions this season. Denver traded its 2010 first-round pick (No. 14) to take Smith at No. 37 in 2009. Denver gave up on him and traded him to Detroit in September.
