"He's the one that's healthy," Tomlin said.
Roethlisberger is recovering from a sprained medial collateral ligament and bone bruise. If he practices without limitations and is cleared medically, Tomlin would not stand in the way of his return.
Backup quarterback Mike Vick started in Roethlisberger's absence but he left the Week 6 win over the Arizona Cardinals in the third quarter with a hamstring injury and was replaced by Jones, who led four second-half scoring drives to help the Steelers win.
. Since the beginning of the 2010 season, when Roethlisberger was suspended for four games by the NFL, the Steelers are 7-4 with a slew of backups, including Vick.
Roethlisberger practiced on a limited basis last week and was ruled out of the Arizona game on Friday.
