Last year, after an off season that saw the quarterback in the headlines for sexual assault allegations, his teammates chose to not vote him a team captain, the Pittsburgh Tribune-Review reported.
This year's team vote to return the title to him was seen as a vote of confidence.
"He has done a great job of opening himself up to the team and keeping his nose clean," lineman Willie Colon said.
Roethlisberger had been voted offensive co-captain in 2008 and 2009.
"Anytime you are voted captain by your teammates, it means a good deal to you," tight end Heath Miller, who replaced Roethlisberger as captain last year, said. "Ben has come back and has become the leader of this team, and that was indicative today."
