Twins third baseman Trevor Plouffe has been placed on the seven-day disabled list after showing concussion symptoms following a collision at second base late in Tuesday night's loss. Plouffe was examined by a doctor at Turner Field, but has yet to undergo a full impact test. That will happen in a few days back in the Twin Cities. "I passed the concussion test last night, but my initial reaction to the incident kind of made them think twice about it," Plouffe said Wednesday morning. "I was really foggy and sensitive to light. Those are all symptoms of a concussion." Chris Colabello was recalled from Triple-A Rochester to take Plouffe's place on the roster. Colabello was scheduled to start in right field, batting sixth, in Wednesday's series finale against the Atlanta Braves. Plouffe said he felt "a lot better" Wednesday, but it typically takes a few days for a medical staff to properly diagnose a concussion. "I slept like a baby last night," Plouffe said. "They said that was also a symptom." Plouffe said he suffered a "minor concussion" while playing at Rochester, where he spent parts of the previous five seasons. He said he couldn't remember which year that happened or the exact circumstances. "That was a little more drastic than a blow to the head," he said. "It wasn't a pitch or a knee to the head. To be honest, I don't even remember."
