"Re-signing Roman was a top priority as we look to regroup heading into the 2013-14 season," said Predators GM David Poile.

Roman's skating ability and instincts have allowed him to play in all key situations.
"With today's signing, we have our top defensive pairing locked up long-term, and we look forward to Roman's continued development and contribution to the Predators' on-ice success."
