Grasu is entering his fifth season in the league and has spent time with the Bears, Ravens, and Dolphins since entering the NFL in 2015. The two-time college All-American will now reunite with quarterback Marcus Mariota, who was Grasu's teammate at Oregon during their time in college.
The Dolphins waived Grasu on Sunday, Safid Deen of the South Florida Sun Sentinel reports.
The Dolphins needed depth in the secondary, so they promoted safety Maurice Smith from the practice squad while cutting Grasu. The fourth-year pro could be a practice squad candidate if he clears waivers.
Grasu was waived by the Ravens on Saturday, Jamison Hensley of ESPN.com reports.
Grasu was primarily serving as the backup for starting left guard Alex Lewis. Given the amount of depth on the Ravens' offensive line, he was ultimately the odd man out in favor of bulking up on defense.
Grasu was a third-round pick by the Bears in 2015 and was with them before being waived during final roster cuts this offseason. The fourth-year center will look to revive his career with the Ravens and help an offensive line that has struggled so far in 2018. To make room for Grasu, the Ravens waived defensive back Robertson Daniel.
