The extent of the injury was discovered during an MRI performed Tuesday and he has decided to see a foot specialist in Charlotte, N.C. by week's end.
"I have a hard time sitting on the sideline for a bruise. That led me to believe that it was a little more pain than just your average bruise," Jones said on the Braves' Web site.
"They (doctors) assured me there is quite a bit of trauma to the bone. I was worried about whether or not it was a tendon or a ligament. I wanted to make sure it was messed up."
The former first-round draft pick by the Braves in 1990 could miss the rest of the season if surgery is necessary.
Currently, he is on the disabled list and will wear a special boot to immobilize his foot for three or four weeks. Jones initially was injured on April 24 and re-injured his foot Sunday during an at-bat against Pittsburgh.
Jones was batting .282 with seven home runs and 26 RBI.
