Smith, 23, was drafted in the seventh round by Carolina out of UNC in 2018. He was entering the third year of his four-year, $2.5 million deal when the Panthers traded him to the Bills in exchange for a conditional 2023 seventh-round pick.
Smith bounced on and off the Bills’ practice squad last season. He was set to be a restricted free agent.
In 2020, Smith appeared in 12 games and recorded nine total tackles, one tackle for loss, no sacks, and one forced fumble.
