Twitter is all ablaze after Merritt Paulson tweeted a new RB will be added to the Timbers Roster VIA trade. Mike Donovan (@themikedonovan) then tweeted this:

My random guess is Kosuke Kimura

MP replied to Mike Donovan with: Later MP replied to a different comment from Mike Donovan with:

@TheMikeDonovan I'd say your guess was a good one

Now MP has sent out this tweet:

New right back arrived at training and none of our players from earlier this week are now "former Timbers" ;)

I will update as we get more information.

UPDATE

Portland could also trade Jonathon Bornstein's rights to Colorado and thus satisfying MP's statement Portland now has no Former Timbers.
