Wall revealed the sad news about his mother's cancer during an interview with NBC Sports Washington's Chris Miller earlier this month.
"My spirits are great, man. Just spending time with my son, spending time with my mom that's battling cancer," he said.
"God don't make no mistakes. I can't wonder why He did this, probably it's a good time to spend with my mom while she's battling this cancer and be there for her, and also be there for my son."
