Neil Lennon looks likely to be locking horns yet again with the Scottish Football Association following Celtic's William Hill Scottish Cup semi-final defeat by Hearts at Hampden which saw him march on to the pitch to confront referee Euan Norris after the Hoops lost to a late penalty.
Extra-time appeared probable when Parkhead striker Gary Hooper levelled Rudi Skacel's opener with four minutes remaining. However, in the 90th minute Norris dramatically pointed to the spot after a shot from Jambos skipper Marius Zaliukas hit the arm of Joe Ledley and substitute Craig Beattie, a former Parkhead striker, scored to set up the first Hearts versus Hibernian final since 1896.
Lennon, who has three disciplinary cases pending, was further enraged when Norris refused the Clydesdale Bank Premier League champions a penalty in injury time when the ball appeared to come off the arm of Hearts defender Andy Webster.
The former Celtic skipper did not turn up at the post-match press conference but coach Alan Thompson confirmed the Northern Irishman had been into the referees' room afterwards.
He said: "I think he has been in, yes but I wasn't there so I don't know what was said.
"We are all angry. We have just lost the semi-final of the cup when there were 92 minutes on the clock, it is frustrating."
