ESPN first reported the news.
It's so far unclear why his deal with the Raiders fell through.
In an effort to make up for the loss, the Raiders are signing former Browns defensive back Damarious Randall to a one-year deal worth up to $3.25 million, Rapoport reported on Friday.
Hardly your average offseason, Apple's return to free agency isn't the first -- and is unlikely to be the last -- deal to be scuttled in 2020.
Defensive lineman Michael Brockerswas headed to the Ravens, but after a physical, the deal was nixed and Brockers re-signed with the Rams. Cornerback Darqueze Dennard was bound for the Jaguars, but the two sides could not agree on final terms and that deal fell through.
Dennard is still a free agent and so too is Apple.
Now, he's leaving Las Vegas before he officially arrived.
