It appears that Kosuke Kimura wasted no time in getting back into the game during the MLS off season and perhaps in part because he knew a huge shake up was coming for the Portland Timbers. Regardless, according to Wisla Krakow's website, the current Portland Timbers right back defender is on trial with the club, which plays in the first division football league: Ekstraklasa.
According to the website:
Monday tests the team Wisla Krakow defender Kosuke start Kimura Japanese. Player of the season recently ended in the American MLS league where teams represented the Colorado Rapids and Portland Timbers. He is currently a free agent.
Forgive the rough translation, Google apparently is a bit rusty with its Polish.
In any case, there are two things here worth mentioning:
First, the site has him listed as player of the season. I'm not sure what that's referring to or if it's a bad translation on Google's part, but it certainly wasn't true of this season. They could be referring to his time spent with the 2010 Colorado Rapids.
Second, it also mentions that he is a free agent.
If so then this could mean the Portland Timbers have already made their first round of cuts, or simply that Kimura's contract with the Timbers is up and Portland either decided they didn't want to renew, or Kimura decided to try his luck in Europe.
We'll be following up with this information as we get it, but considering that this news is coming from Wisla Krakow's website and features a picture of Kimura wearing their kit, I'm inclined to believe it.
As of this writing, Kimura was still listed as being on the roster for the Portland Timbers.
UPDATE: Now a video interview with Kimura in Warsaw:
