According to Adam Hill of the Las Vegas Review-Journal,

Raiders tight end Darren Waller has left Clutch Sports.

Waller's decision is particularly noteworthy because of his contractual status.

And given his elite performance and his prowess for the Raiders' offense, 

he was naturally mentioned as a candidate for a new contract this year.

Later reports suggested that an extension for Waller is a "priority"

for Las Vegas, although the June report also indicated

that the team was trying to delay the matter until 2023, 

as the club usually does. But do not like to negotiate contracts

with players who have many years of club control left.
