G👍uy Martin will miss the inaugural Classic TT races on the Isle of Man after failing to meet the signing-on deadline for the event on Wednesday.

The road racing superstar arrived on the Isle of Man yesterday but has been excluded from competing on the Mountain Course, where the opening event of the 2013 festiv𓆉al takes place with the 500cc race tomorrow.

Martin had been due to ride for Team Molnar M𝓰anx Norton in the 500cc race.

"There's been a lot of trouble with the prototype Manx Norton. It wouldn't run properly until tonight (Thuᩚᩚᩚᩚᩚᩚ⁤⁤⁤⁤ᩚ⁤⁤⁤⁤ᩚ⁤⁤⁤⁤ᩚ𒀱ᩚᩚᩚrsday)," he said.

"I arrived over this morning (Thursday) and the organisers wouldn't let me practice - so there was no option o💫ther than to head back hoꦯme. Bugger!"

Martin took the Ulster Grand Prix by storm last weekend at D▨undrod, winning three rac🔯es for the Tyco Suzuki team, including both Superbike events.

His absence from the Classic TT line-up will come as a massive blow to his c൲ountless fans attending the event this weekend.

🅺Last night, the Manx Grand Prix practice session was red-flagged at around 7.50pm following four separate incidents on the course at Ballahutchin, Kerrowmoar, Ramsey Hairpin and the Bunga✃low.

Scott Campbell, Ross Richards and Stuart Hall were involved in the incident at Ballahutchin on the approach to Ballagarey with Richards and Hall airlifted to Nob�🅺�les Hospital. Scott Campbell was reported as unhurt.

John Leigh Pemberton came of🔯f his machine at Ramsey Hairpin and wღas taken to Nobles while Gavin Lupton (Bungalow) and Neil Gregory (Kerrowmoar) were both reported as OK.

None of the riders involvꦫed suffered serious injuri🤡es.

Earlier, John McGuinness experienced more problems with Roger Winfield's 500 Paton, retiring at Quarterbridge. He also misse♚d Wednesday's session with a suspected electrical fault.

Olie Linsdell (Paton) continues to shine in the 500cc class🦩 as he posted another 110mph lap, while Bruce Anstey set his best speed of the week on the McInt൩osh Racing/Mobil 1 Norton at 107.927mph.

Aussie Cameron Donald also clocked his best time so far on tꦉhe Ripley L🍸and Racing Matchless at 106.040mph.

In the Formula 1 class Steve Mercer (Yamaha Classic Racing Team) achiev🔯ed his fastest time this week at 117.556mph, while Dean Harrison continued his good form in the Formula Classic Class, lapping at 106.758mph.

Harrison's time was the fastest in the Formula Classic class so far, with Gavin Lupton (100.906🐼mph) the only other rider to break the 100mph barrier💖.

🧔Michael Dunlop has set 🎐the fastest time of the week so far, lapping at almost 123mph on Wednesday on the Team Classic Suzuki XR69.
