ALAMEDA, Calif. (AP) The NFL is investigating whether a video linked to an account from suspended Oakland Raiders linebacker Aldon Smith shows him using illegal drugs.

A video on a periscope account that has shown Smith in the past features an unidentified man off camera discussing a rolled cigarette with an unidentified woman. It's not clear what's in the cigarette and who the man is. Smith sent out a tweet Monday after CSNBayArea.com reported on the video saying ''Good try, not me.''

NFL spokesman Brian McCarthy says the league is investigating.

Smith is serving a one-year suspension for violating the league's substance abuse policy that ends Nov. 17. He can apply for reinstatement in September. He gets regularly drug tested while on suspension.
