Plouffe had sustained the concussion May 22 when he was kneed in the head by Braves second baseman Dan Uggla while trying to break up a double play. He was activated the first day he was eligible, but his calf began cramping during sprints before Wednesday's game.
Plouffe said it was a relief that his concussion-like symptoms lasted only a few days, compared with the issues that Justin Morneau experienced for more than a year after sustaining a concussion in July 2010 and the problems that plagued Denard Span for several months in '11.
"Initially it was something I was pretty worried about, seeing Morneau and Span go through the same thing," Plouffe said. "I leaned on Morny for some advice, and he just said to be honest with yourself with this. And I did that, and luckily for me my symptoms went away after the third day, and I've been champing at the bit to get back since then."
Twins manager Ron Gardenhire was also happy to have Plouffe activated after missing a week. Plouffe was riding an eight-game hit streak before sustaining the concussion in Atlanta.
"He's excited to be back and has done all his work," Gardenhire said. "He was approved to play, so it's nice to have him back out there."
Gardenhire also explained the rationale for optioning Colabello, who went 1-for-11 in five games after being called up when Plouffe landed on the DL. Gardenhire opted to keep Chris Herrmann on the roster because of his ability to catch and play the outfield, while Colabello is a first baseman with limited experience in right field.
"I've got first basemen and I've got right fielders," Gardenhire said. "Right now, we need versatility."
