Tavon Austin remains out

EARTH CITY, Mo. -- St. Louis Rams receiver Tavon Austin again did not practice Thursday as he continues to recover from an ankle injury.

Austin suffered the injury Dec. 8 against Arizona and has not played or practiced since, missing games against New Orleans and Tampa Bay. Rams coach Jeff Fisher has expressed optimism the past couple of weeks that Austin might be able to return in time to get back on the field, but time is running out for that to happen.

The Rams have one more practice Friday before traveling to Seattle for the season finale. If Austin doesn't at least get some work in at practice, it seems likely his season will end without another appearance.

Elsewhere on the injury report, the Rams were without safety T.J. McDonald because of an illness and running back Daryl Richardson did not practice because of a thigh ailment.

Defensive end Chris Long returned to practice as a full participant after sitting out Wednesday with a thigh injury.
