Former Chicago Bears running back Adrian Peterson mourned the loss of his son on Tuesday.
Peterson's son A.J. lost his battle with Diffuse Intrinsic Pontine Glioma (DIPG), the same type of cancerous tumor Lauren Hill has been fighting and raising awareness for. A.J. was diagnosed with the inoperable brain tumor back in June.
