Learn Texas Holdem

First I want to tell you I enjoy your website a lot, lots of really good information and tips to play better, so thank you. I was wondering if you can help me answer a question: see some of my friends and I were playing texas holdem, the community cards show: 2d, 5d, 7d, 10d, and Kd so there is actually a flush of diamons in the community cards, now the other players don't have a better hand than the one showing in the community cards except for one player that has an 8 of diamonds, now my question is can that player use his 8 of diamonds to make a higher flush by removing the 2 of diamonds from the community cards and win the hand or does it have to be a tie?

Again Thank you very much for your help and for taking the time to read this e-mail.
