Michael Sam, 1st openly gay player in NFL draft, stepping away from football, he says; 'The last 12 months have been very difficult for me, to the point where I became concerned with my mental health. Because of this I am going to step away from the game at this time. I thank the Alouettes for this opportunity and hope to be back on the field soon. Thank you all for your understanding and support' - @MichaelSamNFL
