Bradley was initially listed as probable for Friday's game against the Sacramento Kings. However, an MRI taken on Thursday evening revealed the injury.
Bradley signed a two-year, $9.7-million deal with the Lakers this offseason. The 10-year veteran is a noted 3-point shooter but has struggled from distance this season, connecting at a 28.6% clip through 10 appearances.
However, Bradley has been a welcome addition to the Lakers' top-ranked defense. L.A. has allowed just 98.6 points per 100 possessions with the former first-round pick on the floor, per NBA.com.
