NFL conducting comprehensive investigation of Manning

Rivera says the 11-year National Football League veteran may need to wear a brace on his arm similar to the one New England Patriots tight end Rob Gronkowski wears.

But he did so with the caveat that he could earn back every penny by getting to and winning Super Bowl 50.

League spokesman Brian McCarthy says the inquiry, which began weeks ago, involves reviews of records, interviews and coordination with other agencies.

Meanwhile, the game featured a matchup between two legendary rival quarterbacks in the Patriots’ Tom Brady and the Broncos’ Peyton Manning.

Its source – Texas-based pharmacist Charlie Sly – has since recanted.

NFL Network cameras caught an intriguing exchange between Manning and New England coach Bill Belichick after Denver’s 20-18 win over the Patriots in the AFC championship game on Sunday.

“Hey, listen, this might my last rodeo”.

At the time, Manning was recovering from neck surgery suffered during his spell with the Indianapolis Colts.

Belichick responded, “You’re a great competitor…” Manning is the only QB to take multiple teams to the Super Bowl multiple times.

But the 39-year-old quarterback declined to revisit the past, including the foot injury that sidelined him for six games this season.

Manning angrily denied using performance-enhancing substances and called the report “complete garbage”.
