CHELSEA goalkeeper Filip Jorgensen had a laser shone in his face as he prepared to defend a corner.
The Swedish-Danish youngster, 22, got a rare start between the stick for the Conference League trip to Panathinaikos on Thursday.
But when the Greek side got ready to launch a set-piece into the danger area after 14 minutes, he was distracted by a laser.
The green beam could clearly be seen on Jorgensen's face.
An announcement was put out over the PA system at the Olympic Stadium in Athens.
However, it was seemingly ignored by some as Enzo Fernandez also had his face lit up in green during the first half.

And the offence could prompt a fine from Uefa as punishment to Panathinaikos for their fans' behaviour.
Chelsea fans took to X, outraged by the use of a laser pen - which is an all-too-familiar occurrence in Greek football.
One fumed: "So Panathinaikos fans are doing laser in the face of Chelsea players? How classy."
Another wrote: "Why are Panathinaikos fans pointing laser pens at Chelsea's players?? Why?"

And a third added: "Nothing says Conference League like laser pointers on the faces of Chelsea players!"
Earlier on, Panathinaikos paid an emotional tribute to their former defender George Baldock.
Baldock died tragically in the swimming pool at his Athens home on October 9 aged just 31.
A live band played a version of David Bowie's Starman ahead of kick-off, the song Sheffield United used for his chant during his time with the club.
Fans in both the home and away end held up cards with Baldock's No32 on, while 32 flags bearing the number were waved pitchside.
Supporters also displayed a homemade banner reading "George Baldock, Immortal" in Greek in the club's first home game since his sudden passing.
Players from both sides, who took part in a minute's silence ahead of the game, wore black armbands while the Chelsea squad also posed with a Blues shirt with "Baldock, 32" printed on the back.
Baldock's team-mates appeared close to tears during the minute's silence, with manager Diego Alonso having said the club were still in a state of mourning.
Panathinaikos players and staff plan to travel to England for Baldock's funeral later this month, while the club are also considering honouring the remainder of his three-year deal to support his family.
