Charlotte Bobcats leading scorer Kemba Walker is expected to be sidelined for 10-14 days because of a sprained left ankle, the National Basketball Association (NBA) team said on Sunday.

Walker, 23, who is averaging a team-high 18.7 points and five assists per game for the Bobcats this season, suffered the injury in the third quarter of Saturday's 104-96 overtime loss to the Miami Heat.

Though subsequent X-rays were negative, a magnetic resonance imaging (MRI) exam on Sunday revealed a second degree sprain for the guard, who is widely regarded as one of the most exciting young talents in the NBA.
