Swimming and Martial Arts

Hello everyone! :) Im new here , and I would like to help me in something here! Well, I was playing football from the age of 7 and im 18 now! I was very good and I had an invitation to an other country! But I didn't went because of my injury! I stopped footbal cause of that! They said me to start swimming because I have a nice body and a good heart! (Thank god :D). Never mind, I started swimming everything is good! I love that sport! But I still play football but not in a team! With some other team with bet and in 5x5 - 7x7 - 8x8 championships! What's my question now? I want to start martial arts but not stopping swimming! Im doing 3 times a week swimming in about 50 minutes each practise! Can I make them both without any injures or problems? Thanks in advance! :)
