Quarterback Ben Roethlisberger, who has spent his entire professional career with the Pittsburgh Steelers, is leaving the field. The quarterback, dubbed “Big Ben,” made the announcement on Thursday via Twitter: “The time has come to clean out my locker and hang up my cleats and continue to be all I can be to my wife and children. I retire from football a truly grateful man.” Roethlisberger has been with the Steelers for 18 years, leading the team to two Super Bowl victories. The first was against the Seattle Seahawks in 2006 and the second in 2009 against the Arizona Cardinals. During his football career, Roethlisberger was accused of sexual assault twice, once in 2009 and again in 2010. He denied the allegations.
