Washington: Denver Broncos quarterback Peyton Manning, yet to confirm he will return for an 18th NFL season, reportedly starts off-season training work this week with a trainer specializing in older athletes.
The New Orleans Times-Picayune newspaper reported that Manning has been evaluated by Mackie Shilstone, a famed fitness trainer whose client list includes tennis world number one Serena Williams, baseball`s Ozzie Smith and boxers Bernard Hopkins and Roy Jones.
Hopkins, who turned 50 last month, became the oldest fighter to unify major boxing titles last April when he beat Beibut Shumenov for the World Boxing Association and International Boxing Federation light heavyweight crowns, titles he lost to Sergey Kovalev last November.
Williams, 33, won her 19th Grand Slam singles title last month at the Australian Open, becoming the oldest woman to capture that crown.
Manning, who turns 39 next month, is the NFL`s oldest starting quarterback and underwent multiple neck operations before joining the Broncos in 2012 after having led the Indianapolis Colts to a Super Bowl victory in 2007.
Manning, a five-time NFL Most Valuable Player, threw for 4,727 yards and 39 touchdowns last season, putting him among the NFL`s most productive passers. The Broncos were ousted by Indianapolis in the NFL playoffs last month.
Should Manning return, he needs only 2,148 yards to break the all-time NFL career passing yardage mark owned by former Green Bay Packers star Brett Favre.
