A recent heart exam on new Sacramento Kings big man Chuck Hayes shows an abnormality that will require further testing. The Kings announced Thursday night that a stress echocardiogram revealed the abnormality. The former Houston Rockets forward-center signed a $21.3 million, four-year deal with the Kings last week. Hayes averaged 3.4 points and 4.7 rebounds in 17 minutes per game in six seasons with the Rockets.
