Carrier, 31, originally signed on with the Raiders as an undrafted free agent out of Beloit College back in 2012. He spent a year with the Eagles before joining the 49ers at the start of the 2013 season.
Carrier was later traded to Washington in a deal that sent a 2017 conditional fifth-round pick to San Francisco. Washington wound up trading him to the Rams in exchange for a 2018 seventh-round pick back in 2017.
From there, Carrier signed a three-year, $7 million deal with the Raiders before being released earlier in the week.
In 2020, Carrier appeared in all 16 games for the Raiders and caught one pass for 14 yards.
