Rio KO fear

RIO FERDINAND has left Manchester United in a Euro sweat after he spent the night in hospital.

Ferdinand went off near the end of Wednesday’s 1-0 win over Arsenal.

But SunSport can reveal the England defender, 30, stayed in hospital all night after damaging ribs in a collision with his own keeper Edwin van der Sar.

United now fear he will miss the return leg of their Champions League semi-final at The Emirates on Tuesday night.

United boss Alex Ferguson admitted after the match that he feared Rio, 30, might have cracked a rib.

Medics were still assessing the situation last night but Ferdinand is definitely out of tomorrow’s Premier League game at Middlesbrough
