The San Francisco 49ers have waived Greg Mabin with a "waived/injured" designation after the 25-year-old cornerback suffered a calf injury during practice on Wednesday. The team also officially announced the signing of cornerback Quinten Rollins to a one-year deal, which was first reported by Matt Maiocco of NBC Sports Bay Area.
The Tampa Bay Buccaneers signed Mabin as an undrafted free agent out of Iowa on May 1, 2017. He spent time with the Buffalo Bills before being signed to the 49ers practice squad on October 18, 2017. San Francisco promoted Mabin to the active roster on November 1, 2017.
Mabin appeared in 13 games with one start in 2018 while registering 16 combined tackles and a forced fumble, per NFL.com. San Francisco waived the cornerback on October 30, 2018, and re-signed him to the practice squad on November 1, 2018. The 49ers promoted Mabin to the active roster on November 8, 2018.
Mabin has recorded 18 combined tackles, two passes defensed, and a forced fumble through his two NFL seasons.
The Green Bay Packers made Rollins a second-round selection out of Miami (OH) in 2015. He registered 91 combined tackles, a sack, 16 passes defensed, three interceptions, and a touchdown through 33 games during his three seasons with Green Bay. Rollins finished the 2017 season with the Packers on injured reserve due to a non-contact leg injury sustained during Week 6. He spent part of last season with the Arizona Cardinals.
