Barcelona will be without one of their best players for the next few games.

According to multiple reports, Neymar has been diagnosed with the mumps. This comes as a bit of surprise because the Brazilian striker was previously vaccinated. The mumps is a very contagious disease, so head coach Luis Enrique is taking precautions.

Barcelona had the following statement: "The first team medical staff at FC Barcelona has announced on Sunday that Neymar will be out for two weeks after being diagnosed with parotitis (mumps), despite the fact that he had previously been vaccinated against the disease."

Because of the unexpected news, Neymar will miss the 2015 UEFA Super Cup against Sevilla. If Barcelona can defeat Sevilla on Tuesday, that will give them five UEFA Super Cup championships, which would tie them for the most of all-time with AC Milan. It obviously won't be easy without Neymar on the field.

In addition to missing the UEFA Super Cup, Neymar will also miss the 2015 Spanish Super Cup. This event has two legs featuring the winner of last year's La Liga champion (Barcelona) and the runner up of the Copa del Rey, Athletic Bilbao. Barcelona and Athletic Bilbao will play each other on Friday, Aug. 14 and again on Monday, Aug. 17. Both games will be played in Spain.

There's zero chance whatsoever that Neymar will play in any of those three games, but the concern doesn't end there. The beginning of the Spanish Premier League is nearing. Barcelona's opening game is against Athletic Bilbao on Aug. 23. It hasn't been confirmed whether or not Neymar will miss Week 1.

Barcelona are the defending La Liga champions.

Many soccer experts believe this will have a big impact on Pedro. The 28-year-old forward has been at the center of rumors lately about his transfer to Manchester United, but Barcelona may want to hold on to him for insurance.

As far as value is concerned, Neymar is regarded as one of the best players in the league (and world) today. Last season he scored 22 goals. Only Lionel Messi and Cristiano Ronaldo found the net more often than Neymar did last season. His exit at the Copa America against Colombia was very disappointing, and you can bet Neymar wants to rebound in a big way.

Missing the first game or two shouldn't cost Barcelona a great deal considering it's a 38-week season.
