The Blazers have announced via twitter that Brandon Roy has left the team to fly to Seattle to get a second opinion on his hamstring. Blazers trainer Jay Jensen has accompanied Roy to Seattle. Roy's departure has also been reported by Brian Wheeler at 95.5 The Game. Roy is listed as out for the rest of the road trip. As Ben has announced on our twitter page, Jay Allen (also from 95.5 The Game) is speculating that Roy could be out until the All-Star Break.
Update (3:41PM): Here's a full post from Joe Freeman of The Oregonian which notes, among other things, that Jerryd Bayless will continue to start in Roy's place.
And here's a full post from Casey Holdahl over at Blazers.com that features an update on Nicolas Batum, who was cleared for full-contact workouts today.
