Cristiano Ronaldo has been included in the Portugal squad for their World Cup play-off against Bosnia-Herzegovina.

The Real Madrid forward faces a race to be fit for the two games on November 14 and 18 as he has an ankle injury.

Medical reports from the Primera Division side on Saturday said he would be out of action for at least two more weeks.

Ronaldo has missed Madrid's last eight matches after suffering an injury to his right ankle during the Champions League match with Marseille on September 30, and then aggravating it while playing for Portugal in their World Cup qualifier against Hungary on October 10.

The world's most expensive player on Thursday met with Dutch specialist Professor Niek van Dijk in Amsterdam after tests conducted by Madrid on Wednesday revealed that no improvement had been made on Ronaldo's injury since undergoing an MRI scan the week before.

Van Dijk, who operated on the 24-year-old's right ankle in the summer of 2008, advised Ronaldo to continue his treatment before returning for a fresh evaluation in two weeks' time.

Portugal coach Carlos Queiroz revealed on Saturday, however, that the injury would not stop him from naming Ronaldo in his 23-man squad, so important is the former Manchester United man to his country.

Valencia full-back Miguel, Wolfsburg centre-back Ricardo Costa and Werder Bremen striker Hugo Almeida returned to the squad.

Portugal take on Bosnia-Herzegovina in Lisbon on Saturday with the return leg in Zenica four days later.

Full squad: Hilario (Chelsea), Eduardo (Braga), Rui Patricio (Sporting Lisbon); Ricardo Costa (Wolfsburg), Bruno Alves (Porto), Paulo Ferreira (Chelsea), Miguel (Valencia), Pepe (Real Madrid), Ricardo Carvalho (Chelsea), Rolando (Porto); Deco (Chelsea), Duda (Malaga), Joao Moutinho (Sporting Lisbon), Fabio Coentrao (Benfica), Miguel Veloso (Sporting Lisbon), Raul Meireles (Porto), Tiago (Juventus); Cristiano Ronaldo (Real Madrid), Liedson (Sporting Lisbon), Nani (Manchester United), Hugo Almeida (Werder Bremen), Simao Sabrosa (Atletico Madrid), Edinho (Malaga).
