Arizona Cardinals star Kyler Murray agrees to $230.5 million deal, is now among NFL's richest QBs, source says

Arizona Cardinals star Kyler Murray has agreed to a five-year extension worth $230.5 million, 

a source told ESPN's Adam Schefter, a deal that makes him one of the NFL's highest-paid quarterbacks.

The deal, which runs through the 2028 season, includes $160 million guaranteed for injury, the source told Schefter.

Murray will make $105 million fully guaranteed upon signing the deal, according to the source.

The average annual value of Murray's deal is $46.1 million, which is the second highest in the NFL behind only Packers star quarterback Aaron Rodgers ($50.3 million).

Deshaun Watson's deal with the Browns has an average annual value of $46 million, and Chiefs star Patrick Mahomes' deal averages $45 million per year.

The only deal in NFL history with more guaranteed money than Murray's is Watson's $230 million fully guaranteed with the Browns.

The Cardinals officially announced Murray's five-year extension Thursday but did not disclose terms. 

Some of Murray's teammates, including newly acquired receiver Marquise "Hollywood" Brown and star safety Budda Baker, congratulated the quarterback on Twitter.
