Following the arrest of linebacker Erin Henderson for driving while intoxicated and in possession of a controlled substance on Tuesday, Spielman has called for an improvement from those associated with the franchise.
Spielman said in an official statement via NFL.com: "The fact that we have had three recent off-field situations is unacceptable and disappointing. Our organisation looks at each situation and the circumstances involved to determine our actions with those players and how to best move forward.
"The Vikings have a comprehensive approach with our player development program and excellent resources that are a part of this organization, but certainly we will take a methodical look at how we can improve upon our current programs to prevent these situations in the future."
On the field, the Vikings are currently 2-8-1 in the NFC North.
