Steelers backup quarterback Charlie Batch left the playing field with a fractured right collarbone in the second quarter of tonight's preseason game against the Philadelphia Eagles.
The Steelers won the Heinz Field game, 16-10.
There was no immediate word on how long Batch would be out but it probably would be at least a month and likely more.
Unless the Steelers pick up another quarterback in the meantime rookie Dennis Dixon likely will serve as No. 2 with rookie Mike Potts No. 3.
Batch left the field with 5:59 left in the second quarter one play after he ran six yards on a broken play. He took the next snap and handed off to Gary Russell, then walked off the field with a team doctor.
Dixon replaced Batch in the lineup.
The Steelers took the opening kickoff tonight and drove 80 yards for a touchdown to take a 7-3 lead over Eagles at the end of the first quarter.
Santonio Holmes caught a quick third-down pass near the line of scrimmage from Ben Roethlisberger and ran 19 yards down the left sideline for a touchdown to stake the Steelers to a 7-0 lead.
The Eagles came right back on their first possession to score on David Akers' 28-yard field goal late in the quarter.
Philadelphia took the lead early in the second quarter on Donovan McNabb's third-down, three-yard pass to Jason Davis. The Eagles stayed with their first team offense while the Steelers deployed their second-team defense on that drive.
Jeff Reed tied it at 10-10 with a 20-yard field goal late in the second quarter and the score remained tied through the third quarter.
