The 49ers designated Alexander to return from injured reserve a few weeks ago and indications were that he was going to return for their first playoff game, so this isn’t a big surprise.
Alexander, 25, is a former fourth-round pick of the Buccaneers back in 2015. He played out the final year of his four-year, $2,758,320 contract before agreeing to a four-year contract worth $54 million with the 49ers in 2019.
In 2019, Alexander appeared in eight games for the 49ers and recorded 34 tackles, a half sack, an interception, a forced fumble and four pass defenses.
Street, 22, was selected in the fourth round of the 2018 NFL Draft by the 49ers. He is entering the second year of his four-year, $3,070,200 rookie contract that included a $610,200 signing bonus.
Street, unfortunately, suffered a torn ACL during a private workout for the Giants during the predraft process last year and has yet to appear in an NFL game. San Francisco placed him on injured reserve coming out of this year’s preseason before being designated to return.
In 2019, Street appeared in three games for the 49ers and recorded four tackles.
During his four-year college career at N.C. State, Street recorded 120 tackles, 19 tackles for a loss, eight sacks, two forced fumbles, four recoveries, and five pass defenses over the course of 46 games played.
