By now, fans have heard that Great Britain’s Barclays ATP World Tour Finals representative Andy Murray has withdrawn from the tournament due to a groin injury.

After a rough first round match against Spaniard David Ferrer ending in a straight sets loss, Murray was forced to make an even rougher decision. A somber Murray told press on Tuesday that his decision to withdraw was a difficult one.

“I knew in my head I wasn't ready to play and wasn't right to play” Murray explained. “That's why it's disappointing. It's just a really difficult decision to make because it's one of the best tournaments in the year to play and it's something that you also work all year to play here, as well.”

After a promising season came to an ill-fated end, Murray couldn’t hide his disappointment. “Not being able to play is what's most frustrating,” Murray said “Because, like I said, you work the whole year to be part of this group of players.”

Murray is set to play in the Australian Open in January, although he admitted some hesitance due to “having a few niggles.” The decision to withdraw from Barclays was made after weighing the pros and cons of continuing in the tournament. After deciding that further injury could damage his preparation for the Australian Open, the Brit said so long to London.
