Chiefs’ TE Travis Kelce is being placed on the Reserve/COVID list, sources tell ESPN.

Schefter said Kelce is vaccinated so there’s a chance he’s back for Sunday with the new return-to-play protocols.

The Chiefs used a lot of multiple tight end formations during Reid's early seasons. From 2014 through 2017, they were in the NFL's top 10 every season in number of plays out with three tight end personnel groupings. They led the league in that category in 2016.

But the Chiefs since moved away from those formations as they improved at wide receiver, adding first Tyreek Hill and later Sammy Watkins and Mecole Hardman. They used no three tight end formations in either 2018 or 2019 and though they did use two tight ends on occasion, Travis Kelce was on his own a lot in terms of his position.

That will change this season.

The story said the Chiefs may not always use all four TEs at one time, but they have tinkered with it in practice and the preseason, especially close to the goal line. And, they've had success with it, scoring a TD against the Vikings in the preseason. Four TEs on the field would obviously be bad news for Hill owners because it would mean he's not on the field in those situations. Gray could be a player to keep an eye on as he's the team's fifth round pick from this year's NFL Draft.

Andy Reid confirms some of the key starters won't play Sunday against Chargers. "Certain guys will have the opportunity to rest up,'' he said.

No specifics were mentioned but one has to assume Mahomes, Kelce, Bell and Hill could be among those not to dress, or at the very least see limited time in Week 17.

If Chris Herndon stays healthy, the Jets will be set at tight end according to Connor Hughes of The Athletic. "It’s fun watching how Gase uses Herndon, too," wrote Hughes. "While he has traditional tight end abilities (he’s a very good blocker), the Jets line him up all over the field. While I don’t think Herndon will ever be in the same class as Zach Ertz or Travis Kelce, he creates so many matchup problems for defenses."

Hughes addressed the issues at wide receiver in the same article, which also bodes well for Herndon. QB Sam Darnold turned lemons into lemonade with Ryan Griffen in 2019, so the uber-talented Herndon should dwarf his numbers as long as he remains on the field. Herndon has the opportunity to be a top 10 tight end in 2020.

Tight end Travis Kelce officially signed a contract extension with the Kansas City Chiefs. Terms were not disclosed.

Kelce is locked in with the team that has allowed him to flourish and become an elite producer at tight end. The Patrick Mahomes-Kelce connection will roll on for at least the next few seasons.

According to ESPN’s Jeremy Fowler, the Kansas City Chiefs and star tight end Travis Kelce have agreed to the parameters of a four extension.

With George Kittle setting the market, both Travis Kelce and the Kansas City Chiefs had an established ballpark to work around, which allowed the talks to rapidly progress. Kelce and the Chiefs had been in discussions for a while, and they have now agreed to an extension that will keep him in Kansas City for six years. The deal is not yet official, so no specifics have been released, but Ian Rapoport suggested that it is between $14 and $15 million AAV in new money, with $25 million guaranteed. Travis Kelce has been one of the top receiving threats in the league regardless of position for years now, and this extension will keep him as one of Patrick Mahomes top targets for years to come.
