Two Days Ago I Was Playing Football I Was Blindsided

Two days ago I was playing football I was blindsided and hit in the ribs, I had The air knocked out of me for only a second and then I continued playing. It was until after the game I felt pain. It hurts to stretch a certain way and if I take deep breath sometimes, but I don't feel any pain when I sneeze, cough or laugh. Are My ribs fractured or are the muscles on my ribs just badly bruised?
