The Tennessee Titans placed cornerback Tye Smith on injured reserve, the team announced Tuesday.
The team did not disclose the nature of the injury Smith sustained. He appeared in 15 games and had one interception with the Titans in 2017, making one start.

The 6-foot-5, 283-pound Maxey spent the final month of the 2017 season on the Titans' practice squad. Maxey appeared in two games with the Pittsburgh Steelers in 2016.
Lampkin (6-foot-4, 335 pounds) is an undrafted free agent out of Oklahoma. He appeared in 15 games over two seasons with the Sooners, recording 27 tackles, including 6.5 for loss, and one sack.
Pelon appeared in one game with the New York Jets in 2017, making a pair of tackles.
