Robin Singh will have to sit out the remainder of the competitionAIFF Media

The Indian national football team have a major worry ahead of their SAFF Cup 2015 semifinal match against Maldives on Thursday.

Star striker Robin Singh, who fell down awkwardly before scoring his second goal against Sri Lanka in India's opener of the tournament, has been ruled out for the remainder of the competition.

The lanky forward thereafter didn't take part in India's latest game against Nepal. National coach Stephen Constantine earlier said that Robin's injury wasn't serious, but the player's MRI report has revealed otherwise.

"Yesterday's (Monday's) MRI revealed that his knee problem is a bit more serious than we had expected," Constantine was quoted by AIFF Media. "The doctors have advised us that he will need 10 days rest before undergoing another MRI.

"It's a blow and a loss for us. He had started to score for the National Team on a regular basis and is such a hard working guy."

The Blue Tigers therefore have only 19 players available in their squad for the semifinal match against Maldives. Sunil Chhetri, Holicharan Narzary and Jeje Lalpekhlua are the options for Constantine in the striking position.

Wonder kid Lallianzuala too can play as a central striker, but it is highly unlikely Constantine will deploy the Mizoram star as a lone forward in the upcoming game.
