According to GPOne.com
, the LCR Honda team will run Roger Lee Hayden, younger brother of 2006 MotoGP champion Nicky Hayden, as a substitute for the injured Randy de Puniet in this weekend's US Grand Prix at Laguna Seca.
de Puniet broke his left tibia and fibula during Sunday's German Grand Prix.
Roger Lee Hayden is racing for the uncompetitive Pedercini Kawasaki team in World Superbike this season, but has plenty of experience of Laguna Seca from racing in the AMA championships and finished tenth in the 2007 US MotoGP as a wild-card for Kawasaki.
Roger is due to race an American Honda-backed Moriwaki entry in the Indianapolis Moto2 round later this season.
There is still no news on whether Aleix Espargaro, involved in the same accident as de Puniet, will be able to race in the USA after scans found a cracked vertebra.
Checks are being made to establish if it is an old (in which case he can ride) or new injury.
