Houston Texans outside linebacker Duke Ejiofor tore an anterior cruciate ligament during practice on Friday, the Houston Chronicle reported.
The injury is expected to be season-ending.
Ejiofor, 25, was a sixth-round pick for the Texans in 2018. He played in 12 games as a rookie and finished with nine tackles, a sack and fumble recovery. He also appeared on special teams.
Ejiofor missed the entirety of the 2019 NFL season after tearing an Achilles tendon last year.
A native of Houston, Ejiofor was a standout at Wake Forest, where he registered 23.5 career sacks.
