World number four Dominic Thiem has withdrawn from this month's Monte-Carlo Masters, saying he is still not ready to compete.
Thiem has endured a disastrous start to the season, starting with a disappointing fourth round straight-sets exit to Grigor Dimitrov at the Australian Open.
Things didn't get any better for him afterwards, with him suffering early exits in both Doha and Dubai while starting to talk a little more about a foot injury that emerged last season.
He pulled out of the Miami Masters after those losses, saying he needed to 'reset' in practice for the clay season instead, but things don't appear to be going entirely to plan.
"After Doha and Dubai I needed a break," Thiem explained on his official website.
"I‘m not at 100% yet. I‘m so sorry, I would have loved to play in Monte Carlo, but it won‘t work out."
"I‘m having tough weeks ahead of me, I have a lot of work to do."
Thiem is scheduled to play in Belgrade the week after Monte-Carlo after choosing not to defend his Barcelona title, which is taking place in the same week.
It isn't known whether Thiem's foot injury has contributed to the decision, although both he and his father have been adamant, publicly at least, that it is not an issue.
