O'Neal, who is averaging 13.5 points and 9.5 rebounds, stayed
down for a minute before walking gingerly to the bench. He returned
after a timeout but missed both free throws before being replaced
by Kris Humphries and hobbling into the locker room alongside the
trainer. A team official said O'Neal would undergo further tests.
Williams appeared to yank the bottom of O'Neal's jersey as
O'Neal was going up for a shot under the basket early in the
fourth. O'Neal fell back awkwardly, clutching at his left thigh,
above a brace he wears on the knee.
O'Neal missed 40 games last season because of lingering pain
from a torn ligament in his left knee that was surgically repaired
the previous summer. He joined Toronto in an offseason trade that
sent guard T.J. Ford to Indiana.
