Poor Ms. Rihanna hurt her foot during an all day rehearsal for her upcoming world tour, which starts in September. The good news is her injury is minor and will be all healed within two weeks. Although, she will have to perform her Denver show in a chair. I'm pretty sure she will get some choreographer to work with her situation and make the show interesting. If anyone attends, try to take some footage. I am curious to see how she handles it.
