Teenage sensation Carlos Alcaraz has been dealt a major blow with injury forcing him out of this month's Australian Open.
The world No 1 was one of the favourites to prevail at Melbourne Park, having won his maiden Grand Slam title in September at the US Open. The 19-year-old underlined his potential by beating Casper Ruud in the final at Flushing Meadows.
However, the end of his season was plagued by a torn abdominal muscle, which forced him to miss the ATP Finals in Turin. The Spaniard was also unable to represent his country in the Davis Cup Finals, eventually won by Canada.
