Angry Shrewsbury boss Graham Turner confronted referee Tim Robinson after his penalty U-turn cost his side all three points at Brentford.
The veteran manager went into the match official's dressing room after the goalless draw at Griffin Park to demand an explanation for his 71st-minute decision. The referee pointed to the spot after the ball cannoned off Tony Craig's hand above his head, but reversed the decision after talking to his assistant.
Three points would have been just reward for Turner's side following a spirited display which saw them pile the pressure on Brentford's nervy defence.
"In the circumstances I do consider that two points dropped, but I just can't understand the referee's decision,'' he said. "The rules clearly state that if the ball strikes the hand in an unnatural position then it's a penalty, and you don't get much more unnatural than that."
It was a view shared by Bees boss Uwe Rosler, who said a lack of confidence in front of goal was all that is standing between his side and a good run of results. But his charges wasted a host of chances and were booed off by sections of the crowd frustrated at their side's inability to break down a well drilled Shrewsbury rearguard.
The Londoners had goalkeeper Simon Moore to thank for earning them a share of the spoils, denying Terry Gornell's smart header with a reflex near-post save. The early substitute, who also smashed a 77th-minute effort against the woodwork, linked well with lively target man Marvin Morgan, who twice scuffed shots wide when well placed.
Turner added: "I was very pleased with the passing and movement and with two back-to-back away games that's a good point on the board. It should have been three but what was said in the ref's room will remain between us."
Clayton Donaldson fired a first-half effort against the outside of a post after a superb Adam Forshaw through ball for the hosts, while Paul Hayes had the ball in the net as he diverted a Harry Forrester cross home but his effort was ruled out for offside.
Bees boss Rosler bemoaned the number of times his front men were caught offside by a disciplined Shrewsbury side. "There is no need for that when you have the pace we have up front, but I do think the strikers are a little short on confidence. Goals will solve that though,'' he said.
"I thought it was a penalty having seen it on video, but I thought a draw was a fair result and also felt that Shrewsbury were very strong and caused us a lot of problems."
