Leftwich injured his non-throwing arm when it was pinned awkwardly to the turf while he slid for extra yardage during the third quarter. Steelers coach Mike Tomlin said Monday he's not ruling out an eventual return by Leftwich and, in the meantime, is in no hurry to choose a No. 2 quarterback behind starter Ben Roethlisberger.
The Steelers started training camp with four quarterbacks on their roster, with either Charlie Batch or Dennis Dixon -- the only two quarterbacks remaining on the roster -- certain to be jettisoned before the Sept. 11 season opener against the AFC North rival Baltimore Ravens. Batch and Dixon now have a reprieve from an unforgiving numbers game and don't have to worry about losing their jobs, although the backups would rather have taken a different path to a steady paycheck.
The duo has spent the last month auditioning for the No. 3 spot behind Leftwich and Ben Roethlisberger. Now they head into Thursday night's preseason finale at Carolina looking to see who will be Roethlisberger's understudy.
The anxiety of being cut is gone, sure, but not the competition.
"You still have to go out and prove to Coach Tomlin that you're capable of being the next guy to step in, and it never ends," Batch said. "It's not going to end at the end of this week ... or through the course of the season."
Batch said it was difficult to watch his good friend writhing in pain as he was taken off the field. Yet Batch also knows the job goes on, leaving he and Dixon in a familiar position.
A year ago, the two spent camp jockeying for position behind Leftwich, who was dubbed the starter after Roethlisberger was suspended four games for violating the NFL's personal-conduct policy.
Only Leftwich never made it to the regular season after injuring his knee. Dixon started the opener against Atlanta and played well before going down one week later with a knee injury of his own that eventually sent him to injured reserve.
In stepped Batch, who turned back the clock by helping keep the Steelers afloat until Roethlisberger returned.
A year later, the two players on opposite ends of their careers are still going at it.
Batch, 36, is simply hoping to hang on while Dixon, 25, is anxious to prove he's ready to be a starter, even if he's well aware it will have to happen in someplace other than Pittsburgh.
The former University of Oregon star re-signed with the Steelers after no other team expressed sincere interest in him. Knowing this was likely his last camp in Pittsburgh, Dixon has been heavily showcased during the preseason, playing extensively in all three games. The results have been mixed. Dixon is 10-of-24 passing for 132 yards with an interception while playing with the third- and fourth-stringers who likely will be long gone in a week.
"My main goal has been my leadership skills, commanding the huddle, making sure everybody is on the right page," Dixon said. "Usually when I go in the game, I'm with people that don't know what they're doing half the time."
Dixon used to consider himself among that group. Not anymore.
"I've been in the system long enough to where I have confidence as to what I'm doing," Dixon said. "If I do mess up, I'm going to go 100 percent at it."
Batch lacks Dixon's mobility and youthful exuberance, but he has proven adept at walking into adverse situations after joining the Steelers as a backup in 2003. He has appeared in 27 games for his hometown team, sometimes in blowouts, sometimes in nail-biters.
"That's the dirty part of being a backup, you don't know when your number is going to be called," Batch said. "It could be the first week, it could be Week 17. At the end of the day, nobody cares when your number is called ... it's just a matter of going out there and helping your team win."
Dixon and Batch should have plenty of time to make a case for themselves against the Panthers. Roethlisberger likely will only play briefly, giving his backups a chance to see some rare work with the first-stringers.
"This may be the last week you get your reps with the actual starters," Batch said. "During the course of the regular season, Ben gets all the snaps with the ones, and we get whatever's left over and it's not much. You have to make sure you hone your skills this week."
They aren't the only ones hoping to receive extended looks Thursday.
Wide receiver Emmanuel Sanders is hoping to play after spending most of camp battling a stress fracture in his foot. He feels ready to go and is anxious to make up for lost time.
"I'm a competitor and I want to be out there," Sanders said. "There's some good football going on out there in the preseason, and I've missed three (games). And I want to get out there. I want to play."
And Batch and Dixon certainly want to give him the ball, and give themselves a chance to be No. 2 in the process.
