American Ben Spies sat out the final day of testing Thursday at Sepang to rest his shoulder, which underwent major surgery after last season.
Spies struggled on the first two days on his Pramac Ducati due to weakness in his shoulder area. He elected to play it safe Thursday and instead focus on building overall strength before the next test Feb. 26-28 at Sepang.
"These three weeks rehabilitation have not been enough," Spies told German media. "I'm physically not where I should be. But I have, with my coach, for the next two and a half weeks already prepared a very extensive training program. I'm flying with him now to Australia."
Spies ended up 15th overall at 2:03.002, a daunting 2.902 seconds behind the leading pace of Dani Pedrosa's Honda.
"I had to be careful especially when braking," Spies said. "I didn't want to do anything crazy and risk a new injury."
