An MRI didn't reveal any structural damage, but there is inflammation in the area and the Blue Jays don't want to take any chances and risk further complications.
"He's going to make sure it's gone," manager John Gibbons said of the inflammation. "Last time we tried that and it didn't work."
Injured third baseman Brett Lawrie remains on the mend, but according to Gibbons, is still a couple of weeks away from starting a rehab assignment. Lawrie has been out since May 27 with a sprained left ankle and has begun taking ground balls and batting practice, but he is still limited in his overall workload.
In other injury news, left-hander J.A. Happ recently began throwing off a mound but is still "a ways away" from getting back into games. Happ, who is on the 60-day disabled list, will have to make multiple rehab starts since he hasn't pitched since May 7 in St. Petersburg, where he was struck in the head by a line drive off the bat of Desmond Jennings.
Right-handed reliever Sergio Santos will throw a bullpen session at Tropicana Field on Tuesday afternoon. Santos underwent a minor surgery to clean up bone spurs in his right elbow on May 19, and this will give Gibbons and pitching coach Pete Walker an opportunity to see him throw in person.
