“Words cannot describe how heartbroken we are in the loss of our friend, Brian DeLunas,” head coach Steve Bieser said. “In the months since his return to Mizzou, he has made an indelible impact on our team through his love of the game and his players along with his inspirational courage off the field. Brian was a tremendous husband, father, brother and coach, and our hearts go out to Johannah, Rory, Maren and the entire DeLunas family as we ask everyone to keep them in your thoughts and prayers.”

SEC commissioner Greg Sankey also shared his condolences to the Mizzou family:
