Stand-in Leeds goalkeeper Paul Rachubka was distraught after his mistake handed Coventry a 1-1 draw at Elland Road.
Coventry defender Richard Wood turned the ball home at the far post after a fumble by Rachubka to cancel out Darren O'Dea's first-half opener for the home side.
Leeds manager Simon Grayson revealed Rachubka, making his first league start for the club due to first-choice Andy Lonergan's fractured finger, was inconsolable in the dressing room.
Grayson said: "Goalkeeper is a position where you make a mistake and you get punished. He won't let me down again. It's just one of those things.
"His head is in his hands, but he'll pick himself up. He'll be fine, I've no problems with him.
"Andy Lonergan will be out for six weeks after having an operation on his finger.
"It's a blow to the lad because he's been outstanding and it's a blow for the team, but I've a good, capable keeper to stand in."
Grayson's side passed up the chance to climb back into the top six, but he was still pleased with their overall performance, except for a nervous final 10 minutes.
He added: "We took our foot off the gas. We just didn't keep hold of the ball enough or work them hard enough.
"We had enough chances. The second goal is always vital in any game, but unfortunately we couldn't get it."
Leeds' 10-goal leading goalscorer Ross McCormack lifted a gilt-edged chance over the crossbar with just goalkeeper Joe Murphy to beat at the end of the first period with the hosts a goal to the good.
And Murphy made inspired saves to deny Danny Pugh and Adam Clayton in the second half, while Robert Snodgrass flashed a raking drive inches wide.
Coventry had created little until Cyrus Christie's desperate cross to the far post in stoppage time was spilled by Rachubka, allowing Wood to pounce.
