Las Vegas previously tendered Carlson with a second-round tender.
The second-round tender will cost $3.384 million for the 2021 season and ensured that the Raiders would get a second-round pick should Carlson have received an offer sheet from another team.
Carlson, 26, is a former fifth-round pick of the Vikings back in 2018. He was in the first year of his four-year, $2,708,012 contract when the Vikings waived him a few months in to the regular season.
The Raiders later signed Carlson to a contract and he finished out the year in Oakland. The team again opted to sign him to another one-year deal back in April of 2020.
In 2020, Carlson appeared in all 16 games for the Raiders and made 33 of his 35 field goal attempts at a rate of 94.3 percent and making 45 of his 47 extra point attempts.
