Update: Looks like Jeremy Maclin is expected to play.
Kansas City Chiefs WR Jeremy Maclin has been out all week with the concussion he suffered in last week's loss to the Minnesota Vikings and it's not looking good he will be available on Sunday against the Pittsburgh Steelers. The same goes for DE Mike DeVito, who also suffered a concussion in that game and has been out all week.
Players with concussions who don't practice all week usually aren't playing in a game on Sunday. The Chiefs still have a practice on Friday so there's hope but it's certainly not looking good. The Chiefs will be getting extra looks at WRs Albert Wilson and Chris Conley who figure to step in if Maclin can't play.
"It's a big task for (Wilson and Conley)," Chiefs OC Doug Pederson said, via quotes from the Chiefs, "they're going to get multiple reps obviously and extended play. You've got to rely on, I think, not only those guys, but Travis Kelce and your running game. There's other pieces to the puzzle that you can lean on and you're just hoping that Jeremy can play in the game."
Also of note on the injury report is that LB Justin Houston was upgraded from a limited practice to a full practice on Thursday.
