Raiders' Aldon Smith: Subject of league investigation

Smith (suspension) will be investigated by the NFL for a potential violation of protocols required for a player seeking reinstatement from a suspension for violating the substance abuse policy, ESPN.com reports.

Analysis:

Smith is currently serving a one-year suspension as a repeat violator of the league's substance abuse policy, but he could be subject to further discipline after a video recently circulated of an unidentified man, suspected to be him, talking about a hand-rolled cigarette shown on screen. The video is titled "Fire up session" and archived in a Periscope account Smith has used and clearly appeared on over the past two months. No stranger to off-field transgressions, Smith is eligible to apply for reinstatement in September, but the results of the league's investigation could ultimately impact his case and future availability altogether.
