Diego Costa has been included on Spain's 23-man roster for the World Cup.

Costa has been dealing with a hamstring injury, which was worsened in last week's Champions League Final.

David Villa and Fernando Torres were also included.

Fernando Llorente and Alvaro Negredo were among the final cuts for Vicente del Bosque.

Juanfran made the roster despite fitness concerns, while Dani Carvajal and Alberto Moreno will stay home.

Jesus Navas is another high-profile player who won't be going to Brazil due to injury issues.

Vicente del Bosque is unsure of Diego Costa's fitness ahead of the World Cup for Spain.

Costa tore his hamstring in Atlético Madrid's Champions League defeat to Real Madrid.

Del Bosque must finalize his 23-man roster by June 2.

"I'm not sure Costa will make it," Del Bosque told reporters.

"We've still got time but now it's in the hands of the doctors and the medical team. We have to be cautious," he said.

Rafael van der Vaart has been ruled out of the World Cup after picking up a calf injury in a training session on Tuesday.

The 31-year-old Hamburg midfielder, who has 109 international caps and appeared at the 2006 and 2010 World Cups, was in contention to make Louis van Gaal’s 23-man squad.

Luis Suárez has texted his Liverpool teammates that he will be in the Uruguay lineup when they face England in the second Group D game on June 19.

Suárez underwent keyhole surgery on a knee injury he first suffered in Liverpool's final game of the season.

Jordan Henderson is one of the five Liverpool teammates on England's team.

"Everybody is obviously disappointed for Luis, people that know him – maybe not us – because he is a big player for Uruguay," said Henderson.

“I gave him a text to see if he is doing all right and wished him good luck with whatever he has got to have done.

“But I am sure, knowing the type of person he is, he is a fighter and I am sure come maybe the first game or the second game in the World Cup, I am sure he will be ready and raring to go.”

Aaron Ramsey has dismissed rumors that he will need to undergo surgery to repair his thigh injury.

"Please ignore any stories about me needing surgery," Ramsey wrote on Twitter. "They are completely false. I'm enjoying my summer and already can't wait for pre-season.”

Ramsey scored 16 goals to go with 10 assists in all competitions last season.

Diego Costa and Cristiano Ronaldo increased their workout activity on Thursday with both returning to training with their teams ahead of Saturday's Champions League Final.

Costa remains a major doubt for the game having been diagnosed with a grade 1 hamstring tear last Monday, but having undergone a "miracle" horse-placenta treatment in Belgrade this week.

Ronaldo is expected to start no matter what as he comes back from a thigh muscle injury.

Luis Suárez underwent surgery on Thursday after suffering a meniscus injury on Wednesday.

Uruguay remains confident that Suárez will be healthy in time for the World Cup.

“His participation at the World Cup has not been ruled out," said Uruguay in a press release. "In terms of relevant clinical history, it is worth noting hat he suffered a blow to his left knee during the last game of the Premier League season with Liverpool, which provoked a pain that subsided with rest following the end of the season.”

Recovery times for meniscus repair for footballers range from three to 10 weeks.

Liverpool have yet to be informed about the extent of the striker’s injury but it is standard practice for a national FA to contact the player’s club when he requires surgery.

Diego Costa has reportedly travelled to Serbia to visit a "medical miracle worker" specializing in horse placenta treatments.

Costa is seeking a quick recovering from a hamstring injury in order to play in Atlético Madrid's all-important Champions League Final against Real Madrid.

Diego Simeone said earlier this week that it was "too soon" to rule the Spain star out of the final, and AS and Marca report that Costa headed to Belgrade to visit Marijana Kovacevic in a bid to expedite his recovery.

Kovacevic is said to use electric shocks as well as ointment made of horse placenta. Robin van Persie has received treatments from him in 2009.

Costa is also a key member of Spain's roster for the World Cup.

Vicente Del Bosque warned that Costa would be taking a risk if he played in the Champions League final.

"It is normal that a player wants to be there, because it is not just another game but the European Cup final," he said. "But he cannot go against his own health. His team, Atlético, and the player himself are those who have to weigh up the situation and the consequences."

Costa will go to Chelsea in the summer on a transfer.

Radamel Falcao has not played since suffering cruciate ligament damage in January, but he remains in Colombia's plans for the World Cup.

"Radamel Falcao Garcia will join his teammates in Buenos Aires," the statement read. "The Colombian striker is currently continuing his physical work with his club side Monaco."

Falcao went from Atlético Madrid to Monaco last summer.

Diego Costa has a grade 1 hamstring tear and will be out for the Champions League Final on Saturday for Atlético Madrid against Real Madrid.

Costa has been the best goal scorer this season for Atleti.

Costa aggravated the injury in the first half of Saturday's match at Barcelona.

Costa should still be available to play for Spain in the World Cup.
