The Buffalo Bills are preparing for their week 4 game against the Pittsburgh Steelers at Highmark Stadium this Sunday. It's the second home game in Orchard Park and will be the only 1 pm home game in the months of September and October, which has been extremely rare for Bills fans.

The 3-1 Bills are currently 14.5-point favorites over the 1-3 Steelers, and what happened Sunday has something to do with that.

The Bills had a huge 17-point comeback against the Baltimore Ravens and other than one drive for a touchdown, shutdown Lamar Jackson and that offense.

The Steelers lost to the New York Jets and will likely turn to a rookie quarterback (Kenny Pickett) starting his first career game in Orchard Park.

But the Bills have injury concerns, and most notably in the secondary and at wide receiver.

The Bills only have three healthy wide receivers heading into this game with Pittsburgh (Stefon Diggs, Gabe Davis, Khalil Shakir).

Wide receiver Isaiah McKenzie is still in concussion protocol, after his concussion against Baltimore, while Jamison Crowder broke his ankle against the Ravens and is now on injured reserve.

Even Gabe Davis isn't "totally" healthy. He went into Sunday's game listed as questionable, still recovering from an ankle sprain he suffered in practice before the Tennessee Titans MNF game. He did not look like himself against the Ravens.

Jake Kumerow is week-to-week with a high ankle sprain and again, we don't know what injury designation Davis (or McKenzie) will have this week.

Chances are that Isaiah Hodgins and Tavon Austin are brought up from the practice squad, but the Bills could definitely sign another receiver this week, just to have enough healthy veterans on the field.

The Bills should still win, even without McKenzie, Kumerow and Crowder, but considering this team passes more than anyone in the NFL, having only two receivers on the active roster that we know are 100 percent (Diggs, Shakir), isn't ideal.

The passing game has not been the same as last season, either. The depth of passes have not been there, especially in the previous two games against Miami and Baltimore. The injuries don't help.
