Atlanta Falcons running back Tevin Coleman, who carries the sickle cell trait, is unsure about playing in the high altitude of Denver next Sunday because it could negatively affect his health.
The blood disorder related to sickle cell disease can cause complications if an individual is under physical stress in extremely hot weather or in environments with low oxygen, such as the high altitude in Denver. Sickle cell trait is a genetic abnormality which can affect red blood cells.
``With my sickle cell, I have no idea if I’ll play there,’’ Coleman told ESPN.
