San Francisco elevated Johnson from the practice squad on Saturday. The defensive back went down on special teams late in the second quarter of Sunday's game against the Tampa Bay Buccaneers. He walked to the locker room under his own power but was later ruled out with a knee injury. That injury ended up being a torn ACL.
The 49ers Communications staff provided the following rundown.
Dwumfour (6-1, 296) originally entered the NFL after signing with the New York Jets as an undrafted free agent on May 2, 2021. Dwumfour was waived by the Jets on August 26, 2021 and later signed to the Houston Texans practice squad on October 13, 2021. In two seasons (2021-22) with Houston, Dwumfour appeared in 10 games (one start) and registered 11 tackles and 0.5 sacks before being waived on December 7, 2022.
This season with Houston, Dwumfour appeared in seven games and recorded six tackles.
A 24-year-old native of Scotch Plains, NJ, Dwumfour attended Rutgers University (2020) after transferring from the University of Michigan (2016-19). Over the course of his collegiate career, Dwumfour appeared in 42 games and registered 61 tackles, 4.5 sacks, two passes defensed and one interception.
Johnson appeared in two games this season.
