Anyone heard anything about the 737-900ER test article, N900ER, being damaged during a tail strike at KEDW?

Funny, I have been to BFI several times in the past couple of weeks and I have not seen N900ER.

Wasn't there something about this in Flight International a couple of weeks ago about the first aircraft being damaged?
Certification of the Boeing 737-900ER is still on schedule to meet its original April delivery target to launch customer Lion Air despite extended testing periods caused by faulty sensors, and additional evaluation for revised stall characteristics and the autoland system.
Windshear disrupts YH001
Boeing has transferred remaining test work to YH002 following an incident during abused landing tests with YH001 at Edwards AFB around 9 February. Boeing says the aircraft "experienced a small windshear event", and that it is "carefully reviewing the data gathered during the flight to ensure that all factors have been considered for the performance data used in the subject condition". External doublers were added to the skin to enable YH001 to ferry back to Seattle for maintenance. Although the shift to YH002 will delay its refurbishment for delivery to Lion Air, Boeing adds that "there is no reason to expect a delay at the moment".
Delays were caused by the unexpected need to replace strain gauges in the horizontal stabiliser around year-end, and by the weather, which refused to co-operate for several days while the test team hunted for suitable crosswinds for the autoland tests.
"We also did some testing with the new leading-edge slat configuration and added Boeing stall testing to that, which used up one or two weeks," adds Craig.
