Alexander will take Foster's position as the 49ers' starting weak-side linebacker.
Alexander suffered a season-ending torn ACL in Week 7 against the Browns, leaving him with 45 tackles in six games in 2018. Adam Schefter of ESPN reports that the deal includes $27 million in guarantees. The person spoke on condition of anonymity because the deal can't be finalized until the new league year starts Wednesday. He tore his anterior cruciate ligament (ACL) on October 22, 2018.

Alexander's most productive season came in 2016 when he led the National Football League with 108 solo tackles and also had 12 tackles for loss.
However, that didn't keep him from making the Pro Bowl that season as he finished with 97 combined tackles and three interceptions, but another injury kept him from building on that campaign last fall.
