(WPXI) – Will Monday night’s game at Heinz Field be the last home game of Pittsburgh Steelers quarterback Ben Roethlisberger’s career? “This is the most important game of the season for us right now,” Roethlisberger said during a press conference. “All signs are pointing to: This could be it. In terms of regular seasons, signs are pointing this way that this could be it.”There’s been speculation that Roethlisberger would retire after this season. “It’s 18 years. It’s almost half my life I’ve given to this city and this team and the fans. I know I still have it in the tank this week to go out there this week and next week and give it everything I have, and do everything I can to get us into the post season,” Roethlisberger said. “I can’t sit here all week and just be nostalgic and think about everything that my career has been when I just have to focus on this game. This is the most important game of the season for us right now.” “My focus is winning this game,” Roethlisberger said. “If it is indeed my last regular season game, it’s going to be one of the most important games of my career.”
