Manx racer Dan Kneen will not compete at next month's Macau Grand Prix.
He hasn't recovered enough from his injuries after a crash at the Ulster Grand Prix in August.
He had been due to race for John Burrows’ B.E. Racing team with whom he has enjoyed so much success at the Irish National Road Races.
Irish rider Brian McCormack is set to replace Kneen as team-mate for Michael Sweeney.
