On UFC 100 this July 11, Brock Lesnar will face Frank Mir on the main event of the night. When Lesnar was still on WWE, I always watch him fight. Now that he's on UFC, I will still suport him. I really want him to win over Frank Mir but I'm sure that Mir will also do his best. I am excited to watch UFC 100 Live Stream Online and see them fight. I hope that Lesnar will defeat Mir. Go Brock!
