The San Francisco 49ers have officially signed Brandon Aiyuk to a contract extension, not only making him one of the highest-paid wide receivers in the NFL but also creating nearly $8.4 million in salary cap space for 2024.
According to Spotrac.com's detailed breakdown, Aiyuk's cap hit for the upcoming season has been reduced from $14.124 million to $5.725 million. The new four-year, $120 million deal includes a $23 million signing bonus, paid out immediately but prorated over the length of the contract. Of the total, $76 million is guaranteed, with $45 million fully guaranteed at signing. The remaining $31 million will become fully guaranteed in April 2025, per the salary cap tracking site.
The contract also includes two void years—2029 and 2030—and provides the 49ers with a potential out in 2027, when Aiyuk's salary cap hit jumps by over $26 million compared to the previous year.
