Howell (thigh) was placed on injured reserve Friday, Aaron Wilson of Sportstalk 790 Houston reports.
EDGE Analysis
The running back will miss at least three weeks before he can be activated, though he is expected to return after the minimum stay on IR. With Darrell Hednerson (thigh) questionable to play in Week 13 against the Jaguars, Howell's absence could leave Sony Michel as the Rams' only healthy option in the backfield for the contest. They would likely elevate someone from the practice squad if Henderson were to be out.
