The 49ers announced that they waived linebacker Mariano Sori-Marin Tuesday evening. The official designation per the NFL’s transaction wire was an injury waiver, although it’s unclear what injury Sori-Marin suffered.
Sori-Marin was signed as one of 12 undrafted free agents after the 2023 NFL Draft by the 49ers out of the University of Minnesota. The former third-team All-Big Ten athlete faced an uphill battle to make a Niners roster that’s already nine deep at linebacker.
Between Fred Warner, Dre Greenlaw, two draft picks in Dee Winters and Jalen Graham, plus Oren Burks, Demetrius Flannigan-Fowles, Curtis Robinson, and Marcelino McCrary-Ball, a roster spot was unlikely to come by for Sori-Marin.
