According to NBC Sports Matt Maiocco, the 49ers have filled cornerback Greg Mabin’s roster spot. Mabin sustained a calf injury on Wednesday. There’s no word just yet if Mabin will go on the injured reserved list, or if he was injured/waived. Mabin was a coin-flip to make the roster, with the ascension of Emmanuel Moseley and D.J. Reed, especially as Reed began to play on the outside more. We’ll provide more details as they become available.
Cornerback Quinten Rollins, who played 33 games with Packers from 2015-2017, is practicing today and has taken Mabin’s spot as well as his number on the roster.
