Walker was injured in the third quarter of Saturday night’s loss to the Miami Heat when he stepped on Chris Bosh’s foot on a fast break layup. X-rays taken at the arena were negative, but Walker had an MRI on Sunday.
Walker left the arena Saturday night on crutches and with his foot in a boot.
Ramon Sessions is expected to start for Charlotte.
The injury will end Walker’s streak of 190 straight games played – the second-longest in team history.
Walker is averaging team highs of 18.7 points, five assists and 1.4 steals this season and has scored in double digits 37 times.
