Jones wasn't allowed to talk to reporters after Friday's practice, but his teammates expressed their belief that Jones would do well if he indeed makes his first career start.
"It looks like Landry," said guard Ramon Foster. "He's the guy we did all the reps with today, and it's Friday. I think Coach is going to make his decision, but it looks like the young guy. We'll see."
Jones, of course, stepped in for Mike Vick last week and rallied the Steelers past the Arizona Cardinals with two touchdown passes to apparent go-to receiver Martavis Bryant.
Jones and Bryant both played their first games of the season last Sunday and appear to be putting together some chemistry.
"That's just through preparation and practice, hard work. Just happens that way, honestly," said Bryant.
Has the 6-4 jumping jack become Jones' go-to guy?
"We've got a lot of great receivers on the field, so whichever one he decides to go to we've got to be there for him," Bryant said.
Tyler Murphy, the undrafted rookie quarterback from Boston College, confirmed that he took all the reps Friday with the scout team and is waiting on a call Saturday for a promotion to the active roster.
"I won't know anything till tomorrow," Murphy said Friday afternoon. "Taking all the scout-team reps today definitely helped. Just trying to get back into the flow of things with timing and footwork. But going against the starting defense, I probably had the best look I'm going to get until the game, if I'm pulled up."
The quarterbacks, of course, would play if Ben Roethlisberger can't. But it appears Roethlisberger will miss his fourth game with a sprained knee that had improved enough to allow him to practice earlier in the week.
Roethlisberger is officially listed as questionable for the game, along with reserve cornerback Cortez Allen (knee).
Ruled out are SS Will Allen (ankle), DE Stephon Tuitt (knee) and Vick (hamstring).
Tuitt's loss will be the most difficult for the defense to overcome, and it appears the Steelers will attempt to do so with more than one man. Nose tackle Steve McLendon, for one, confirmed that he moved over in the nickel Friday and doubled his workload by taking reps at Tuitt's end spot.
"That's why I've been running extra this week, getting extra reps this week," said McLendon. "The big thing is the difference between us and Tuitt. Tuitt is really good at what he does. The only thing we can do is try to hold it down till he gets back."
One other player will be making his first start Sunday: Alejandro Villanueva will open at left tackle in place of Kelvin Beachum, who's out for the season.
Villanueva said it's really not a big deal.
"It's kind of my job, what I get paid to do," said the Army Ranger and Afghanistan war hero.
Not that he's likely to be nervous.
"Well, if you're not nervous that's not good," the 6-9, 330-pound Villanueva said. "You've got to be a little bit nervous. But I've got confidence in my teammates and coaches. I should be good to go."
And the Steelers should be good to go with Jones under center. As long, his teammates say, as the normally flannel-clad Jones doesn't change what got him there.
"If wears a suit, I promise you it'll be the last time he wears it," Foster said in a raucous, post-practice locker room. "Ever hear of ketchup stains? He's not gonna wear that one again. He better come with the same hideous shirt and bad haircut. He BETTER not wear a suit."
