Petrov and Agbonlahor major doubts for Palace tie

Aston Villa skipper Stiliyan Petrov and 12-goal leading scorer Gabriel Agbonlahor are major fitness worries ahead of Sunday’s FA Cup fifth-round clash at Crystal Palace.

Petrov and Agbonlahor suffered ankle and leg injuries respectively during the midweek home Barclays Premier League draw with Manchester United and are regarded as “doubtful” by Villa boss Martin O’Neill.
