Manchester United defender Rio Ferdinand has trained ahead of Tuesday's UEFA Champions League clash with Arsenal.
Ferdinand had to be substituted towards the end of last week's first leg at Old Trafford after suffering damage to his ribs and a bruised lung in a collision with Edwin van der Sar.
He coughed up blood in the United dressing room and spent the night in hospital, although scans revealed there was no major damage.
Ferdinand sat out the Premier League victory over Middlesbrough and there had been fears he would miss the match at Emirates Stadium.
But the presence of the 30-year-old on the Carrington training ground on Monday morning suggests he will face Arsene Wenger's men.
It will come as a major boost for Sir Alex Ferguson to have the reliable centre-back available as United look to protect a 1-0 lead.
But Patrice Evra missed training along with Wes Brown and could be doubtful for the trip to London.
John O'Shea netted the only goal of the game at Old Trafford to give United the edge in their semi-final tie.
