In need of additional depth on the interior of the defensive line, the San Francisco 49ers landed defensive tackle Sebastian Joseph-Day on Tuesday.

According to a team source, Joseph-Day and the Niners agreed to terms on a one-year deal, with it expected to become official before San Francisco resumes practice Wednesday. The Los Angeles Chargers released Joseph-Day on Friday, a move that was somewhat surprising because he was a team captain who had started all 14 games with the team.

The Browns and safety Grant Delpit have agreed on a three-year contract extension, a source confirmed to ESPN.

The deal is worth $36 million, including $23 million guaranteed, a source said.

The Miami Dolphins have agreed to a three-year contract extension with right tackle Austin Jackson, according to a source.

The extension is worth $36 million and includes $20.7 million in guaranteed money. Jackson was a first-round pick in 2020.
