Gamel (knee) will be placed on the 10-day injured list, Brian McTaggart of MLB.com reports.
Gamel hasn't been in the starting lineup the last two days after suffering a left knee contusion during Saturday's game, and the team has since decided that he'll require a trip to the injured list. Jason Heyward and Mauricio Dubon should see more chances in left field while Gamel is on the mend.
