Day was disruptive in Friday's practice, consistently beating his offensive line assignments and recording a tackle for a loss and a sack, Matt Maiocco of NBC Sports Bay Area reports.
Day was claimed by the 49ers from the Jaguars at the tail end of the 2017 season. The 22-year-old recorded 18 tackles and a pair of sacks in a limited role. Day is currently one of the frontrunners to win a backup defensive tackle role in 2018.
Day was claimed off waivers by the 49ers on Monday, Mike Kaye of FirstCoastNews.com reports.
Day was waived by the Jaguars over the weekend, as they were looking to make room on their roster for a few returning players. He had recorded just two tackles (one solo), one sack and one pass defensed across six games prior to his departure from Jacksonville. He will presumably help provide depth on the 49ers' defensive line.
The Jaguars released Day on Saturday, Ryan O'Halloran of The Florida Times-Union reports.
The Jaguars made a few roster moves to activate players coming off the IR-R, and Day was one of the casualties as a result. The 23-year-old will either revert to the Jaguars' practice squad or find a new opportunity.
Day (back) participated in practice Tuesday for the first time since early August, John Oehser of Jaguars.com reports.
Day has been injured for the past few weeks, but could still make the final roster given he performs well throughout the rest of the preseason and gets back to full health. He won't have much IDP value, as he's buried on the defensive line depth chart.
Day (back) was not a participant at Saturday's practice, John Oehser of Jaguars.com reports.
Day currently serves as a depth option on the defensive line, but he'll need to get back to full health in order to compete for playing time.
The Jaguars selected Day in the fourth round of the 2016 NFL Draft, 103rd overall.
Day fell this far for a reason -- he's a small tackle at 6-foot-1, 293 pounds and doesn't boast standout athleticism to make up for it -- but there's reason to believe he has the skill set to overachieve despite his modest athletic attributes. Day was a four-year contributor at Notre Dame and one of the team's best defenders over the last two years, and he should provide Jacksonville with a high-energy, disruptive rotational piece on the defensive line.
