The Dolphins placed Sieler (biceps) on injured reserve Tuesday.
This move was anticipated after Sieler suffered a ruptured biceps in Sunday's Week 9 loss to the Lions. The veteran defensive tackle is scheduled for surgery and will finish his ninth NFL campaign with 24 tackles, including 2.0 sacks. Zeek Biggers, Kenneth Grant and Jordan Phillips could all take on more defensive snaps with Sieler sidelined for the rest of the season.
