St. Louis Rams defensive end Chris Long is considered questionable for Sunday's contest with the Atlanta Falcons.
Long was limited by a hip injury on Thursday, then didn't participate at all in Friday's session.
The 28-year-old has never missed a game over his six-year career with the Rams and is coming off back-to-back double-digit sack seasons.
Defensive back Quinton Porter (thigh) has been declared out after missing the Rams' last two practice sessions. Safety Darian Stewart is also hampered by a thigh injury and has been listed as doubtful.
Running back Daryl Richardson (foot) and tight end Cory Harkey (knee) are both considered probable.
