Isaiah Mack has made his return to Gillette Stadium.

The New England Patriots announced the addition of the 24-year-old defensive tackle to the practice squad on Wednesday.

Mack had been waived last weekend to open a 53-man roster spot for outside linebacker Shilique Calhoun’s activation from injured reserve. Prior to then, the 6-foot-1, 299-pound Chattanooga product checked into a pair of contests for New England while logging 22 defensive snaps and one tackle.

Originally entering the NFL as an undrafted free agent in 2019, Mack played his first 19 games with the Tennessee Titans. He registered eight tackles, 1.5 sacks and one fumble recovery over that span before being claimed off waivers by New England as the calendar turned to November.

Mack went unclaimed to begin the week.

In a corresponding Wednesday move, the Patriots released tight end Paul Quessenberry, who has logged three stints on the 16-man scout team this season after arriving amid training camp in August.

The 28-year-old Quessenberry played defensive end at the Naval Academy, and totaled 80 tackles, 3.5 sacks, one forced fumble and one fumble recovery during his Midshipmen career. He spent the past five years serving in the Marine Corps.

The Patriots host the AFC East champion Buffalo Bills next Monday night.
