The Lions agreed to massive extensions with two of their top offensive stars Wednesday.

Wide receiver Amon-Ra St. Brown agreed to a four-year, $120 million extension, a source confirmed to ESPN, and offensive tackle Penei Sewell is signing a four-year, $112 million deal, a source told ESPN’s Adam Schefter.

St. Brown’s contract includes $77 million guaranteed, the source said. That’s the most guaranteed money for a wide receiver in a single contract in NFL history, according to ESPN Stats & Information research.

Sewell’s contract includes $85 million guaranteed, the source told Schefter, the most for an offensive lineman, according to ESPN Stats & Information. The $28 million annual average salary in his contract is also the largest for an offensive lineman.

In a video posted to his Instagram story from Ford Field, St. Brown said, “I can’t wait. I’m here, four more years.”

Most guaranteed money for WR

Amon-Ra St. Brown’s $77 million guaranteed in his new deal is a new record for a single deal received by a wide receiver in NFL history.

The Lions can now turn their attention to getting an extension done with quarterback Jared Goff. Both parties have entered discussions about an extension, but nothing has been reached yet. Goff is entering the final year of his contract and has expressed interest to remain with the Lions after being traded from the Los Angeles Rams in 2021.

A deal with Goff is not imminent, a source told Schefter.

St. Brown, 24, was selected as a first-team All-Pro last season when he set career bests with 119 catches, 1,515 yards and 10 touchdown receptions.

Sewell, 23, also was selected as a first-team All-Pro for the first time last season. He and St. Brown became the Lions’ first two offensive players to make first team All-Pro since 1997. Both he and St. Brown have been selected to the past two Pro Bowls. Sewell joined Lomas Brown as the only Lions offensive tackles to have been named to the Pro Bowl in consecutive seasons.

Most guaranteed money for OL

Penei Sewell’s $85 million guaranteed in his new deal is a new record for a single deal received by an offensive lineman in NFL history.

St. Brown is one of only three players in NFL history to have 90 or more receptions in each of his first three seasons, joining Odell Beckham Jr. (2014-16) and Michael Thomas (2016-18), according to ESPN Stats & Information.

The Lions selected St. Brown in the fourth round of the 2021 draft. He would have been an unrestricted free agent after this season without a new deal.

Sewell was selected by the Lions in the first round (seventh overall) of the 2021 draft. His extension comes ahead of next week’s deadline for teams to decide on fifth-year options for players selected in the first round of the 2021 draft.

NFL Network first reported the news of Brown’s deal.
