Troy Polamalu has decided to retire after a 12-year playing career, he told the Herald-Standard of Uniontown, Pennsylvania.

Polamalu said the decision to walk away from the game ultimately came down to wanting to spend more time with his wife, Theodora, and young sons, Paisios and Ephram.

"Since the end of the season I've had a chance to enjoy my family on a level that I never had before. It was awesome," Polamalu told the newspaper.

"Thank God football has provided me the ability to be able to sit back and see what the options are. But I'll definitely be the best father I can be."

The Steelers had been patient with Polamalu, who turns 34 later this month, hoping he would retire rather than forcing them to release one of the most beloved and unforgettable players in franchise history.
