Pittsburgh safety Ryan Mundy was fined $21,000 for a brutal hit on Oakland receiver Darrius Heyward-Bey on Sunday, according to ESPN’s Adam Schefter.

Heyward-Bey spent the night in a hospital with neck and concussion issues. He was released the next day and is expected to fully recover. There is no word on when he will be able to play. There was no penalty on the play.

In other AFC West news:

There was a report that Oakland cut second-year offensive lineman Joe Barksdale. However, the Contra Costa Times reports the Raiders said he is still on the roster. Yet, he is not on the practice field. The Oakland Tribune reports Barskdale was brining belongs to his car while practice was in session. This might be a fluid situation. If he is cut, the third-round pick would join fellow 2011 draft picks DeMarcus Van Dyke (cornerback, third round) and Chimdi Chewka (cornerback, fourth round) to be cut since the new regime in Oakland took over.

Kansas City running back Jamaal Charles was named the AFC offensive player of the week after he ran for 233 yards in an overtime win at New Orleans.

Kansas City coach Romeo Crennel said receiver Dexter McCluster will be limited in practice Wednesday. That is good news, because it looked like he suffered a serious elbow injury Sunday at New Orleans. It is not clear if McCluster can play Sunday, but the injury doesn’t seem serious.

Crennel said tight end Kevin Boss is still out with a concussion that kept him out of Week 3. Also, running back Peyton Hillis won’t practice because of an ankle injury.

Denver cornerback Tracy Porter is practicing Wednesday. He left Sunday’s loss to Houston with a knee injury.

Charles is the only AFC West representative on Mike Sando’s MVP Watch this week. He is No. 10. San Diego quarterback Philip Rivers fell off the list after being No. 4 last week. That’s what scoring three points can do to a guy’s candidacy.

The Raiders announced receiver Tori Gurley has been signed to the practice squad. Gurley tweeted Tuesday that he was a Raider.
