Gattis received an anti-inflammatory injection in his right shoulder, which kept him from catching a bullpen session Wednesday as planned, Brian McTaggart of MLB.com reports.

"El Oso Blanco" downplayed the issue, stating that he only got the injection since his shoulder was more sore than he expected to start the season. Gattis hopes to be throwing in the next few days, which is when we'll likely be able to get a better grasp of when he can get back to full activity.
