After proposing to his girlfriend Haley Cavinder in April, he signed a four-year, $52.5M extension during training camp on Sunday.Ferguson's performance suffered a setback in 2024, as he had just under 500 receiving yards for the entire season and failed to score a touchdown. With Dak Prescott missing half of the season due to a hamstring injury, the chemistry with backup quarterback Cooper Rush was never found.After news of the extension broke during the weekend, reporters talked to Cowboys head coach Brian Schottenheimer about Ferguson's new deal. He congratulated his player, but made sure to make a joke at the same time:"Thrilled for Jake and his family, and what he's done, and now he can afford the rock he gave his sweetie."Ferguson became the Cowboys' leading tight end after Dalton Schultz left the franchise for free agency in 2023. He has 1,429 yards and seven touchdowns in his three years with the team.Jake Ferguson proposed to Haley Cavinder on a beachThe pair have been dating since September 2023, just before the tight end started his second season with the Dallas Cowboys.Cavinder posted a picture of her ring on Instagram back in April, and the ring looked stunning, hence the joke by Schottenheimer: View this post on Instagram Instagram PostThe two posted several pictures of Ferguson's proposal, which he did on a beach in front of a wall of flowers.
