JACKSONVILLE, Fla. -- Peyton Manning is entering his 17th season in the NFL while Blake Bortles is entering his second. The two have never played against each other and there’s a good chance they never will.

So Manning’s slip of the lip during a radio interview Friday morning is understandable.

Manning accidentally referred to Blake Bortles as Blaine Bortles. It’s an easy mistake since one of Bortles’ predecessors was Blaine Gabbert.

It’s a bit of a convoluted story, but here’s how it happened:

Manning was being interviewed on the Wake UP Zone show on Nashville radio station 104.5 The Zone, where one of the hosts is former Tennessee Titans tight end Frank Wycheck. Manning was asked about his appearance on Saturday Night Live’s 40th anniversary special and he began to talk about the power of football connecting people.

As an example, he told about meeting Paul McCartney on the set. Surprisingly, the talk turned out to be about the Jacksonville Jaguars. Here’s how Manning explained it:

"I’m thinking there’s no way a Beatle knows anything about NFL or Broncos or whatever and it turns out his wife [Nancy Shevell] has a 20-year-old son who’s a die-hard Jaguars fan and wants to know how the Jaguars are going to be this year, how Blaine Bortles is going to be. Is Julius Thomas going to be good for the Jaguars?

"It’s just that power of football that connects all people so you can have a conversation. So I told Paul he’s got an open invitation to sing the anthem at a Broncos game. I can probably slide him in."

You can listen to the interview here. It's early in the segment.

For those that don’t remember, McCartney has a bit of a connection to Jacksonville, too. He performed at halftime of Super Bowl XXXIX, which was held at Alltel Stadium (now EverBank Field) on Feb. 6, 2005.
