(CNN) -- World number four Andy Murray pulled out of this week's ATP Tour event in Barcelona, Spain on Monday with an elbow injury.
Murray, 23, played Saturday's Monte Carlo Masters semifinal defeat against Rafael Nadal despite carrying the problem and will now rest ahead of the Madrid Open on May 1.
"Under advice from medical experts I have had to withdraw from the Barcelona tournament due to a right elbow injury," Murray, who was seeded second for the tournament in Catalunya, told his official web site.
"I am going to take four-five days rest and begin practicing next week."
The Scot has endured mixed form in 2011; Murray reached his second consecutive Australian Open final in January, where he lost to Serbia's Novak Djokovic, before being eliminated in the first round of February's World Tennis Tournament by Marcos Baghdatis.
Murray has won 16 titles since turning pro in 2005 and reached three grand slam finals.
Another absentee from the clay-court event in the Catalan capital will be Tomas Berdych after the Czech withdrew through illness.
The 2010 Wimbledon finalist has been diagnosed with gastroenteritis and will be replaced in the draw by Rui Machado of Portugal.
