Caitlin Clark's boyfriend reveals death in his family

McCaffery, an assistant coach for the Butler Bulldogs men's basketball team, said his grandmother, Marit Smaby Nowlin, had died.

"I've been trying to think of what to say and I can't. It's impossible to put into words how much you meant to our entire family. I refuse to say goodbye, so until we meet again," he wrote in a touching Instagram post.

Clark commented on the post with hands in prayer and a few hearts. Several others followed her. She missed the Fever's game against the Connecticut Sun on Sunday as she continues her rehab.

"He obviously comes from a basketball family that I know very well, and I'm excited for the impact he is going to have on our program both quickly and in the long run."

Clark has been seen at Butler games supporting McCaffery and the Bulldogs.
