Cincinnati Bengals linebacker Vontaze Burfict has been ruled out of Sunday's game against the Denver Broncos because of a concussion.
He had two tackles in the game before leaving in the second half, bringing his total to just 31 on the year.
The 28-year-old missed the first four games of the 2018 season while serving a suspension for a violation of the NFL's performance-enhancing drug policy. He made his debut in Cincinnati's 27-17 Week 5 win over the Miami Dolphins, finishing with nine total tackles.
