By the time the Union next play, they might be their healthiest all season.

According to Union boss Peter Nowak, the club is using its bye week to its fullest potential. Only rookie Krystian Witkowski, who suffered a concussion two weeks back, is sidelined as a non-participant in training.

Nowak said centerback Carlos Valdes, who has taken hits to his head in three of four matches this season, "is OK" and his fitness shouldn't be questioned for the Union's April 14 match vs. visiting Columbus. Valdes, who wore a padded helmet March 31 against Vancouver, absorbed an elbow to the head from the Whitecaps' Atiba Harris.

Also, Freddy Adu, who was granted “a couple days off” by Nowak, should be fresh when Columbus comes to town. Adu was at PPL Park for the scoreless draw against Vancouver, but didn't make the 18-man gameday roster. He was coming off a stretch during which he played three matches in five days with the U.S. U-23s, who were attempting to qualify for the 2012 Summer Olympics.
