The Rockies activated Karros from the 7-day injured list Friday.
Karros wound up missing a little over a week with his concussion symptoms. He did not embark upon a rehab assignment, but the third baseman ramped up on-field workouts this week to clear the path for his return to the Rockies' lineup. Karros has had a nice first full season in the big leagues, sporting a .265/.361/.424 slash line with 10 home runs in 116 contests.
