American ace Mark Miller has joined the Splitlath Motorsport team.
He will join team-mate Hudson Kennaugh and the pair will ride Aprilia machinery.
Earlier this week, Jenny Tinmouth split with the British Superbike Championship outfit.
Miller has a T.T. win to his name after taking victory in last year's T.T. Zero race.
Kennaugh will compete at the Bank Holiday BSB round at Thruxton before flying to the island on Monday afternoon ahead of the first practice session.
BSB organisers have rearranged Monday's race schedule at the Hampshire circuit to allow around seven riders to fly to the island for the T.T.
