The 49ers on Wednesday signed defensive lineman Cameron Malveaux to a one-year contract.
The 49ers are short on defensive linemen, as Nick Bosa and Dee Ford have been out for more than a week with leg injuries. The club hopes to have both players available for the regular-season opener on Sept. 13 against the Arizona Cardinals.
The 49ers had a roster spot available since Monday, when the club placed linebacker Fred Warner on the reserve/COVID-19 list.
Malveaux (6-foot-5, 265 pounds) originally entered the NFL after signing with the Miami Dolphins as an undrafted free agent in 2017.
He appeared in four games with the Dolphins in 2017. In 2018, he played five games with Miami and four games with the Arizona Cardinals. He went to training camp this summer with Washington but was waived on Aug. 3.
Malveaux appeared in 52 games with 37 starts at the University of Houston. He registered 81 tackles, 17 tackles for loss and four sacks in his college career.
