Titus Davis -- who broke Antonio Brown's WR records at Central Michigan -- has died after battling a rare form of cancer.
He was only 27.
Titus -- older brother of Tennessee Titans wideout Corey Davis -- went public with his diagnosis in July, revealing he was suffering from a rare and aggressive kidney cancer called Renal Medullary Carcinoma.
He underwent chemotherapy to battle to illness -- but ultimately passed away on Wednesday. He's survived by his 2 sons.
Titus was a monster during his 4 years at Central Michigan from 2011 to 2014 -- racking up 3,700 receiving yards and 37 TDs during his career, setting school records in both categories.
