Seahawks left tackle Walter Jones announced via Twitter that he was retiring after an impressive 12-year stint in the NFL that included nine trips to the Pro Bowl. "I have came to the concussion it is time for me to retire from football," Jones tweeted just hours before the start of Sunday's Super Bowl. Jones then followed up a little later to correct himself, saying he meant "conclusion" instead of "concussion." However, neither the team nor Jones' agent, Roosevelt Barnes, could confirm the 36-year-old's retirement plans.
