Former NFL player Alphonso Smith Jr. has reportedly died by suicide at the age of 40. The former Detroit Lions cornerback was found deceased at a housing community in Florida on Wednesday, according to reports from TMZ.

Earlier on Wednesday, a post appeared on Smith Jr.'s Facebook account that spoke of fighting 'demons' and concluded with the phrase 'THIS IS IT!' The post read, in part, "Do not cry for me! I tried everything in my power to fight the demons behind the ones that someone put into ME! I did not want to be that WAY! I know I have disappointed so many folks. This is a DEMON in me! But not only me! It’s EVERYONE! I have HURT so many! I needed help & did not get it!"

Smith Jr. also referred to himself as a 'coward' in the post and offered an apology, stating, "I am SORRY! THIS IS IT!"
