"I'm in the here and now," Roethlisberger said. "That's where we are as coaches and players and a team."
Roethlisberger gamely threw for 330 yards on basically one leg against the 49ers, but his limited mobility restricted the playbook and made every snap an adventure. He tossed three interceptions and fumbled once while failing to get the Steelers into the end zone for the first time in over two years.
NFL Network insider Jason La Canfora cited team sources in reporting this week that the team likely will rest Roethlisberger until the playoffs.
Longtime backup Charlie Batch is 4-2 in spot starts for Roethlisberger over the last six seasons, and though the 38-year-old isn't quite as nimble as he used to be, he and fellow reserve Dennis Dixon have a better chance of getting away from Rams defensive end Chris Long than a hobbled Roethlisberger.
