ST. LOUIS — St. Louis Rams backup running back Trey Watts has been suspended indefinitely for violating the NFL’s substance-abuse policy.

It’s the second suspension this fall for Watts, who was out the first four games.

Watts made his season debut Oct. 25 and had a special teams tackle against the Browns. He was inactive last week against San Francisco after Tre Mason returned from an ankle injury.

Watts signed with the Rams as an undrafted rookie free agent in May 2014 out of Tulsa.
