French swingman Nicolas Batum, projected to be a late first-round NBA draft pick, stopped participating in a workout with the Toronto Raptors earlier this week after a stress echo test -- a treadmill test that measures the health of the heart -- came back in the "borderline" area.

"There is an issue with Batum, and nothing is clear," his agent, Bouna Ndiaye told ESPN.com on Friday afternoon. "The number [the score on his stress echo test] could be a borderline problem if he had a family history of heart problems. But I talked to Nicolas's mother and she said his father didn't die of a heart problem. His team in France and the French national team test him regularly and said they've never seen any indication that he had a heart issue."

A Sports Illustrated report in February said that Batum's father, Henry, suffered a "massive heart attack" and died at the free throw line while playing pro basketball in France when Nicolas was 2 years old. According to Ndiaye, Batum's father died of an aneurysm, not a heart attack.

that's a shame... the scouting reports talk pretty promising of this kid & judging by his online clips he seems like he's got some game... hopefully this isn't serious.
