Victory for John McGuinness in the senior TT race saw Michael Dunlop miss out on a record-equalling fifth win of the event.
Dunlop had taken the chequered flag in the Superbike, Superstock and both Supersport races and needed to win the final race of the 2013 event to equal Ian Hutchinson's five solo race wins three years ago.
The 24-year-old Honda rider could only manage second behind McGuinness after the race had been halted for almost three-and-a-half hours following a crash on the opening lap.
Sheff Pack Kawasaki rider and Isle of Man TT debutant Jonathan Howarth crashed at the Bray Hill section of the mountain course, bringing out the red flags to halt the race.
Although the 29-year-old British rider was not hurt, race organisers confirmed shortly afterwards that 11 spectators were taken to Nobles Hospital with various injuries.
The statement read: "ACU Events Ltd can confirm spectators have been injured during the Senior TT Race, at approximately 13.07, in an incident that involved rider Jonathan Howarth. The rider was unhurt. The race was red flagged and emergency services were in attendance at the scene.
"Eleven spectators have been taken to hospital with injuries ranging from slight to serious. None are believed to be life threatening at this time.
"The police will not be carrying out a full investigation at this stage and it remains a racing incident. The police are currently assisting in clearing the scene and recovering the bike."
The race resumed at 4:30pm and it was McGuinness who would end the day at the top of the podium, finishing 10 seconds ahead of Dunlop.
