Ryan Clark worried about Super Bowls not Baltimore Ravens.

NFL Network’s second-half schedule of Thursday night games kicks off at 8 p.m. ET with an important divisional showdown, as Carson Palmer’s Oakland Raiders battle Philip Rivers’ San Diego Chargers for first place in the AFC West.

Here are a few of my initial observations on the Packers and Steelers after getting a second look at the game during some initial film work on Monday.

Hair was on everybody’s mind during Media Day. Well hair, the lack of it at least, is on my mind every day.

Moments after Steelers safety Ryan Clark donned a wig, he immediately looked over at Troy Polamalu and asked, “Man, how do you do it (play with long hair)?”

In an apparent about-face, starting safety Ryan Clark agreed to stay with the Steelers, a league source told NFL Network insider Michael Lombardi on Monday.

The Dolphins appear close to landing free-agent safety Ryan Clark, according to the Miami Herald. Clark arrived in Miami on Sunday night with the intent of sealing a deal.

Shortly after Antrel Rolle was released Thusday, his agent began looking at potential destinations.

Steve Smith says the Panthers could use some help in the form of a speedy receiver to compliment his game.

The Pittsburgh Steelers have made retaining DT Casey Hampton and S Ryan Clark an offseason priority and neither player is expected to hit the open market, according to sources with knowledge of the situation.

As expected, the Denver Broncos will be without starting RT Ryan Harris against the Pittsburgh Steelers Monday night.

As we reported last week, Steelers safety Ryan Clark will not play in Monday night’s game against the Denver Broncos, according to a league source.

The Steelers listed LB Lawrence Timmons and DE Travis Kirschke as doubtful on the team’s final injury report Saturday, but it’s not looking like either starter will play in Monday night’s game in Denver.

Steelers starting free safety Ryan Clark is highly unlikely to play Monday night in Denver, according to league sources, because of a rare sickle-cell trait that can trigger life-threatening complications at altitude.

Steelers coach Mike Tomlin said Troy Polamalu had a sprained medial collateral ligament, but just how severe the injury is would be “speculation.”
