Jones has been bothered by right wrist soreness for the past few weeks, and stayed in Florida to get an MRI on both hands and wrists during the team's off-day.
The Orioles' public relations department said via Twitter that the MRI, taken in Sarasota, showed contusions on both hands and wrists but that he will be able to play.
Jones, who was pinch-hit for in the ninth inning of Sunday's 8-4 loss to Tampa Bay, had X-rays taken at Tropicana Field after the game. While they came back negative, the team wanted to err on the safe side.
"It just didn't feel right," said Jones, who committed his fourth throwing error of the season on Sunday. "I can feel it when I'm hitting. [The doctors] wanted to get a picture of it, and I wanted to get a picture of it, and see what's going on in there so we can be sure and relieve any doubt."
Jones was hit by a pitch on the left wrist in Toronto on Wednesday night, but said that injury is fine and he's just experiencing "general soreness." His right wrist, however, has caused him more pain. The 26-year-old Jones can't pinpoint how or when it started, although he did feel it again on a third-inning slide.
"Sliding, diving into bags, hitting, playing baseball," Jones said. "It's still strong, it's just sore ... it just hurts."
The Orioles are already playing without left fielder Nolan Reimold and right fielder Nick Markakis. The team's cleanup hitter, Jones is hitting .315 with 16 homers and 34 RBIs, leading the O's in both categories. His presence in the lineup is even more important, given the absence of Reimold, Markakis and second baseman Brian Roberts. Markakis, who had initial X-rays come back negative before discovering a hamate fracture in his right wrist, is expected to be sidelined 3-4 weeks, while Reimold is out indefinitely.
Jones signed a six-year, $85.5 million contract extension a week ago.
"The doctors want to make sure," he said. "Me? I just want to go to Boston. But the doctors want to make sure -- and since we have an off-day, it makes it a little bit better.
"I wanted to hit [in the ninth inning], but [manager Buck] Showalter, he was like, 'Hey, we will take a precaution.' Trust me, I want to hit."
