The Chargers should have their No. 1 running back this weekend. The Steelers probably will not.

Here’s a look at some of the bigger injury news and notes and the fantasy implications as we head into Week 4.

If you watched Thursday night’s game between the Titans and Steelers, it was pretty evident that Willie Parker has lost a step — and some of his fantasy value.

Steelers coach Mike Tomlin will use Willie Parker as his featured back this season, but his recent proneness to injuries still makes Fast Willie a risk-reward fantasy option.

In my latest experts league draft, I decided to focus on wide receivers and passed on taking a second running back until the fifth round. Check out the my full roster to see if this little experiment worked.

The Steelers return 20 of 22 starters, which makes them strong contenders to repeat as Super Bowl champions. They still have Dick LeBeau running the defense, and his players call him “The Wizard,” which reflects the schemes and creativity he brings. The offense still has Ben Roethlisberger under center and returns RB Rashard Mendenhall after a season-ending shoulder injury last year.

Steelers starting cornerback Ike Taylor has restructured his contract to create more salary cap space.

Heinz Field was littered with the remains of broken running backs on Monday night.

The Steelers were already down Willie Parker heading into their game against Baltimore, so losing Rashard Mendenhall for the season puts a serious dent into their backfield depth. The rookie fractured his left shoulder during the overtime win and was placed on injured reserve.

So much for Rashard Mendenhall hurting the fantasy value of Willie Parker.

The veteran has already rushed for two touchdowns (7, 13) in the first half against the Houston Texans. Mendenhall hasn’t seen a single carry in the contest.
