Ravens' Waller suspended at least 1 year for substance-abuse violation

Baltimore Ravens tight end Darren Waller has been suspended by the NFL for a minimum of one year for violating the league's substance-abuse policy.

He also netted a four-game suspension to begin the 2016 season for a violation of the same policy.

Waller, a 2015 sixth-round pick, has just 12 catches across two seasons in the NFL. He may have been in for a bigger role this year, however, after Dennis Pitta suffered his third hip injury in early June and was subsequently released.

The Ravens' depth chart at the position includes Benjamin Watson, Crockett Gillmore, Maxx Williams, Nick Boyle, and Ryan Malleck.
