Don't retire those Troy Polamalu jerseys just yet.
Yes, the Steelers safety legally changed his name Wednesday, but the move won't impact the name emblazoned on the back of the popular No. 43 jersey.
Polamalu -- who was legally known as Troy Benjamin Aumua -- changed his name to Troy Aumua Polamalu, the Pittsburgh Tribune-Review reported on its Web site. The name change became official when Allegheny County Common Pleas Judge Judith Friedman signed a court order during a hearing attended by the football player.
The defensive back out of Southern Cal has gone by Polamalu for the past 15 years, the newspaper reported, and both his driver's license and social security card list the name.
Polamalu is his mother's maiden name, the Tribune-Review reported. His parents divorced shortly after he was born in Orange County, Calif., according to the petition he filed requesting the name change.
