The Jaguars placed Green (elbow) on injured reserve Wednesday.
Green sustained the injury while on punt coverage during the Jaguars' 34-10 win over the Browns in Week 1. The injury is severe enough for him to warrant a stint on injured reserve, meaning he'll be forced to miss at least the next four games. The earliest Green is eligible to return from IR is Week 6 against the Texans on Sunday, Oct. 18.
