Linfield face Uefa sanction over missiles
While Linfield players fought hard on the pitch, the club will likely face punishment over a number a missile-throwing incidents during the match.
As Celtic were celebrating their second goal, a projectile narrowly missed Griffiths.
In the second half, as the same player prepared to take a corner, coins and a glass bottle rained down from a section of the south stand. Griffiths was booked, apparently for time wasting, after protesting.
At that stage, Linfield chairman Roy McGivern went to that area, apparently to confront the troublemakers. But his intervention failed to prevent a number of further incidents.
Linfield were hoping to earn around £1m in prize money, gate receipts, television revenue, advertising and merchandising from this match.
But they could face a fine, and possibly having to play behind closed doors, if disciplinary chiefs take action over the distasteful incidents.
