Barcelona's list of absentees for Wednesday's Copa del Rey final against Athletic Bilbao continues to grow.

Already likely to be without injured trio Thierry Henry, Rafa Marquez and Gabi Milito, Barca coach Pep Guardiola now seems certain to be missing Andres Iniesta and Eric Abidal following the 3-3 draw against Villarreal.

Abidal will be suspended after picking up his second red card of the week during the second half of the draw against Villarreal, while Iniesta sustained a thigh injury.

The Spain international will undergo more tests on Monday to determine the extent of the injury, but Spanish media are suggesting that not only will he miss Wednesday's match but he could also be a possible doubt for the Champions League final against Manchester United on May 27.

Iniesta's stunning injury-time equaliser in Wednesday's Champions League semi-final second leg against Chelsea sent Barca through to the final on the away goals rule.

Treble-chasing Barca, who have not won any silverware since 2006, missed the chance to clinch the Primera Division title tonight after being held at home by Villarreal.
