Following Toronto's 3-2 loss to the Yankees on Sunday, the 38-year-old isn't sure exactly when the MRI will take place, but he said it could happen on Monday after the club returns from its seven-game road trip that was just completed Sunday.
"I think we might take an MRI and see exactly what's going on so we can pinpoint the treatment a little bit better," Dickey said. "George [Poulis] and the training staff, for them to get me out there and ready to compete like they have, they've done a great job."
Dickey admirably has managed to pitch through the pain while delivering solid results on the mound. He has allowed only eight runs over his past 25 1/3 innings, but is only 2-2 over that span in part because of a lack of run support.
The numbers have been there, but Dickey still knows that something isn't quite right. He has every intention of continuing to pitch, but if the exact nature of the injury can be identified, it might help speed up the recovery process.
"I've been pitching with this thing now for about three weeks," Dickey said after allowing three runs in seven innings against New York. "I can do it and still have the results that you saw the last three weeks.
"But I certainly feel like I'm capable of more when I'm healthy. So we'll continue to take it start by start, day by day. You really only have two options, pout about it or grind it out, and I'm certainly going to try to grind it out."
