why did darren waller get suspended

Darren Waller was suspended multiple times in his career for violating the NFL's substance abuse policy. His suspensions were related to substance abuse violations, including marijuana use. For example, in 2016, he was suspended for four games for violating the league's substance abuse policy. Then in 2017, he was suspended without pay for at least one year for another violation of the NFL's substance abuse policy. These suspensions were part of a pattern linked to addiction and dependency issues that Waller struggled with earlier in his life and career, leading to multiple suspensions and even legal troubles. Eventually, Waller sought help, entered rehab, and took steps to rebuild his life and career.
