The World Cup qualifier between Spain and Belarus could be postponed after a generator at the Iberostar Stadium exploded.

The European and world champions are scheduled to take on Belarus at Real Mallorca's home ground tomorrow in their penultimate qualifier.

However, according to Sky Sports News, reports in Spain have claimed that one of three generators exploded due to a technical fault, leaving two people seriously injured.

It is believed that extensive repairs could take too long to be completed in time for kickoff at 10pm local time.

Spain need four points from their qualifiers against Belarus and Georgia to secure their place in Brazil.
