Burnley boss Brian Laws urged his side to be more ruthless in front of goal after they were held to a frustrating 1-1 draw by Doncaster.
The Clarets fell behind in the 13th minute when Jack Cork turned James Coppinger's cross against his own post and James Hayter tapped in the rebound.
Chris Eagles then saw a spot-kick saved by Neil Sullivan after Dean Shiels handled in the box.
Burnley levelled in the 63rd minute as Cork stooped to head home an equaliser, but neither side really threatened a winner.
Laws said: "It was a frustrating night and there's not a lot wrong other than finishing them off.
"If I was going to be critical I'd say we have to be clinical in front of goal. There won't be many games where we have so many gilt-edged opportunities and we won't take them."
