Super emotional scene in the Titans' game Thursday ... Corey Davis played despite his older brother's death Wednesday -- and cameras caught the WR in tears at one point in the evening.
Davis' bro, Central Michigan football legend Titus Davis, tragically died Wednesday at the age of 27 after a lengthy battling with a rare form of kidney cancer.
Corey decided to play a little more than 24 hours later ... because he said that's what his big bro would have wanted.
And, at times during the night, the 25-year-old's heavy heart was apparent.
