Doctors had to wait for swelling in the area to subside before they could get a better read on the healing process and possible damage done to some muscles in the same area. The specialist should be able to determine that and provide a more defined rehab schedule.
"He's feeling better, that's what they say, whatever that means," Blue Jays manager John Gibbons said. "He was having trouble lifting his arm, I know that. He's feeling better, he's progressing but I don't think he can go out there and throw a baseball or swing a bat."
If Tulowitzki is required to miss a full three weeks, that would have him returning on the final weekend of the regular season. That seems to be the optimistic prognosis and there's still no guarantee that Tulowitzki will be able to return for the postseason. Toronto will know more about that relatively soon.
Ryan Goins will continue to fill in at shortstop during Tulowitzki's absence while Cliff Pennington takes over the everyday duties at second. Tulowitzki was hitting .232 with a .314 on-base percentage and a .682 OPS in 39 games since joining the Blue Jays prior to the July 31 non-waiver Trade Deadline.
• Gibbons said that Russell Martin will be behind the plate for knuckleballer R.A. Dickey's next scheduled start on Saturday. Josh Thole has been Dickey's regular catcher since the beginning of August, but the Blue Jays want Martin and Dickey to begin working together again in preparation for the postseason.
• Gibbons also said that right-hander Marcus Stroman has been battling the flu this week. Stroman flew to Toronto early in preparation for Friday's start against the Red Sox and he is expected to be well enough to pitch in that game.
