Diarra injury concern for Pompey

Portsmouth midfielder Lassana Diarra could be sidelined for three weeks, according to manager Tony Adams.

The France international turned an ankle in Saturday's 0-0 draw at West Ham and limped off in the 19th minute.

Diarra is being treated in France following a scan, after the national team insisted he join their squad for their friendly against Uruguay.

"At a club like Portsmouth, injuries have an effect as we haven't the luxury of a massive squad," Adams said.

"We lost Sol Campbell and Niko Kranjcar with injuries before the West Ham game.

"I would like to have scanned him on Sunday and then given them (France) a fair assessment but now we have to wait".

Adams now seems certain to be without the man he regards as his "most influential player" for several games - including Saturday's match against Hull at Fratton Park and their Uefa Cup tie with AC Milan on 27 November.
