Houston Texans defensive end Jonathan Greenard is being placed on injured reserve after he suffered a calf injury in practice this week, a source told ESPN's Adam Schefter.
Greenard is expected to miss four to six weeks, according to Schefter.
He previously missed the Texans' victory over the Jacksonville Jaguars in Week 5 with an ankle injury.
Greenard, a 2020 third-round pick out of Florida, is third on the team in sacks with 1.5 this season after having eight sacks in 2021.
The Texans' pass rush will rely on defensive ends Jerry Hughes, who has a team-high four sacks, and Rasheem Green, who has 2.
