Feyenoord will use its Gran Canaria training camp to assess American goalkeeper Joe Cannon. The San José Earthquakes goalie joined Bert van Marwijk’s squad Sunday, ahead of the club’s trip to the Spanish island. Any decision on Cannon will be made after the squad return to Holland. Cannon is the second American keeper to be invited to the Kuip for a trial. The other was Tim Howard, who didn’t make the cut in Rotterdam.
