The San Francisco 49ers claimed defensive lineman Sheldon Day off waivers from the Jacksonville Jaguars on Monday.
Day was a fourth-round pick by Jacksonville in 2016 and is familiar to 49ers defensive coordinator Robert Saleh, the Jaguars linebackers coach last year.
The Jaguars have one of the deepest lines in the NFL and waived Day over the weekend after they brought receiver Dede Westbrook back from injured reserve.
San Francisco already had an open roster spot after releasing Tony McDaniel last week. McDaniel had served as DeForest Buckner’s backup at defensive tackle in recent games. That likely would be Day’s role as well, although he has experience at both interior positions.
Day, 23, played in six games this season with three tackles, one sack and one pass defensed. San Francisco will play the Houston Texans, Tennessee Titans and Jaguars, all teams familiar to Day, in consecutive weeks next month.
