Marin Cilic has been ruled out of the Australian Ppen after doctors advised him to pull out of the season-opening Grand Slam tournament.
The US Open champion will miss the first major of the year as he continues to suffer with a shoulder problem, one that has dogged his bid to find fitness and form at the start of the 2015 season.
The Croat confirmed his withdrawal to BBC Sport last weekend, admitting: "I am really sad I won't be able to participate, especially after winning the last Grand Slam in New York."
Cilic won't trouble the big four in Melbourne
"I was advised by doctors to be careful as much as possible to avoid anymore serious problems."
"it is improving day by day but i don't feel fit enough to be able to compete at the highest level."

Tsonga also ruled out
He follows Frenchman, Jo-Wilfried Tsonga on the casualty list as the world number 12 also pulled out of the tournament with an arm injury.
The injuries to Cilic and Tsonga have paved the way for British number two, James Ward to be given a guaranteed place instead of having to qualify.
The tournament in Melbourne begins on January 19th.
