In 2012, placements on the seven-day DL have included: Indians catcher Carlos Santana (pictured), Franklin Gutierrez (Mariners), Eric Chavez (Yankees), Josh Thole (Mets), Ryan Sweeney (Red Sox), Bobby Wilson (Angels), Fernando Martinez (Astros), Alex Presley (Pirates), Devin Mesoraco (Reds), Paul Konerko (White Sox) and Jason Bay (Mets); the latter missed 70 days in 2010 with a concussion. Robinson Chirinos (Rays) went on the 15-day DL with a head injury/concussion on March 26 and was transferred to the 60-day DL on April 19. The Orioles’ Brian Roberts missed the first 60 games of this season due to a concussion he sustained in 2011.
Justin Morneau has become the poster boy for concussions in baseball. He suffered a concussion on July 7, 2010, while sliding into second base against the Blue Jays and didn't play the rest of the season. He re-aggravated his concussion in September 2011 while diving for a ball at first base, essentially shutting him down for the season. Prior to the 2011 season, MLB instituted a new seven-day DL intended to give team doctors and the injured players more flexibility to address head injuries.
