(Reuters) - The Charlotte Bobcats exercised a fourth-year option on top scorer Gerald Henderson that will keep the guard/forward with the club through the 2012-13 NBA season, the team said on Wednesday.

Henderson, taken in the first round of the 2009 NBA Draft by Charlotte, is averaging 15.4 points, 4.6 rebounds and 1.8 assists per game this season with Bobcats.

Charlotte, the second-worst team in the league with a 3-15 record, currently is without guard and number two scorer D.J. Augustin, who is sidelined with a toe injury.
