"The last minute withdrawal of Scotland’s Andy Murray from the Swiss Indoors due to injury has not exactly earned the Olympic champion any new fans from within the tennis world. Many people felt that asking for, and promptly receiving, a wildcard into last year’s tournament in Basel and then pulling out again the following year, despite signing a contract, was not really acceptable.

Sounds like a legitimate reason for withdrawal if you ask me. No penalty necessary.
