The Kansas City Chiefs were just three plays into their 2025 season opener in Brazil when they lost one of Patrick Mahomes' key offensive weapons.

Wide receiver Xavier Worthy was ruled out for the remainder of the game against the Los Angeles Chargers with a shoulder injury – and friendly fire is what took him out.

Worthy was running a short route on third down, as was tight end Travis Kelce, when they collided into each other. Worthy got the worst of it as Kelce’s larger frame smashed into his shoulder.

Worthy was in immediate pain on the turf and could be seen on the Chiefs' sideline hanging his right shoulder down and wincing. Trainers appeared to be pushing against it, with some speculating that it was dislocated.

While the Chiefs didn’t specify what exactly Worthy was dealing with, he walked off the field in São Paulo with a towel over his head – clearly disappointed – and never returned.

Worthy, entering his second year with the Chiefs after a solid rookie campaign, was expected to be a top target for Mahomes, especially with the six-game suspension Rashee Rice is serving to start the season. 

The Chiefs and Worthy are both hoping he can have a quick return for next week’s game – a Super Bowl LIX rematch against the Philadelphia Eagles at Arrowhead Stadium.

With Worthy out, the Chiefs had some trouble moving the ball in the first half, while the Chargers quickly got off to a 10-0 lead. The Chiefs were able to get into field goal range twice for Harrison Butker to add six points to the board before halftime. 

Worthy, the Chiefs’ 28th overall pick in the 2024 NFL Draft out of Texas, tallied 59 catches for 638 yards with six touchdowns in 17 games last season. 

In the playoffs, Worthy’s role increased, leading the team with 287 yards and 19 receptions over their three games. He also scored three times, including one in the 40-22 loss to the Eagles in the Super Bowl.

Joe Kennedy III on Friday denounced his cousin Health and Human Services (HHS) Secretary Robert F. Kennedy Jr. as "a threat to the health and wellbeing of every American" in a blistering social media post. 

The rare public rebuke comes one day after RFK Jr.’s contentious Senate hearing, deepening a family feud that has fractured one of America’s most famous political dynasties.

Kennedy’s statement, viewed more than 1.2 million times, opens the curtain behind the extraordinary rift inside the political dynasty. 

Once synonymous with Democrat unity, the Kennedys are now split over RFK Jr.’s embrace of President Donald Trump and his appointment to HHS Secretary under a "Make America Healthy Again" agenda. Joe Kennedy’s demand that his cousin resign marks a dramatic escalation of the feud.

In 2024, five of RFK Jr.’s siblings issued a joint statement blasting his endorsement of Trump as "a betrayal of the values that our father and our family hold most dear. It is a sad ending to a sad story." 

Caroline Kennedy later urged senators to block her cousin’s cabinet nomination, writing in a January 2025 letter that he was a "predator" who was "addicted to attention and power" and "unqualified" to lead HHS.

On Sept. 4, RFK Jr. appeared in a hearing before the Senate Finance Committee. Sen. Ron Wyden, D-Ore., accused him of firing CDC scientists and replacing them with "cranks" and "conspiracy theorists" who were "endangering children, leaving parents confused and scared."

As Joe Kennedy wrote in his post, "None of us will be spared the pain he is inflicting… Those values are not present in the Secretary’s office. He must resign." 

His cousin Jack Schlossberg, President John F. Kennedy’s grandson, piled on in real time, mocking RFK Jr.’s testimony: "RFK LOSER is choking so badly LIVE."

With Robert F. Kennedy Jr.’s controversial tenure in Trump’s cabinet, the Kennedy dynasty’s divisions are now spilling into public view with some of the sharpest blows coming from within.
