ATLANTA -- Chris Colabello's baseball journey from independent baseball has reached the major leagues.

The Twins have added Colabello, veteran of seven seasons in the Can-Am League, to their roster for Wednesday's game with the Braves, calling him up from Class AAA Rochester to replace Trevor Plouffe, who has been placed on MLB's new 7-day concussion disabled list.

Plouffe was kneed in the head by Braves second baseman Dan Uggla during the 10th inning of the Twins' 5-4 loss. To add Colabello to the 40-man roster, the Twins transferred Darin Mastroianni, scheduled for ankle surgery today, to the 60-day disabled list.

Colabello, 29, was batting .358 with 12 home runs and 39 RBIs at Rochester.
