And it's that troubling right foot...
Here's some of the history regarding Lopez's injuries
ESPN
On Saturday, Brooklyn Nets All-Star center Brook Lopez had a third surgery on his right foot at Duke Medical Center in North Carolina. He broke it for the second time on Dec. 20. In addition to fixing the break, part of the procedure was what is known as a first metatarsal osteotomy.
Essentially, doctors moved bones around in Lopez's foot to better bear the weight. It's taking a human appendage that was not truly meant to carry a 7-foot body that runs miles every day and redesigning it.
The surgeries that Yao, Ilgauskas and Lopez have all had were slightly different. A specialist could probably explain in great detail the facets of the procedures and differences in the bones and the alignment of the heel and ankle, etc. But they also were all the same; three big men whose feet couldn't support their profession having their bones moved around to give them a chance. In Ilgauskas and Yao's case, it was a last chance.
