Wonky knee puts Kobe back on the sidelines

Kobe Bryant is expected to miss about six weeks with an injured left knee - the second major injury setback of the year for the Los Angeles Lakers' superstar guard.

An MRI exam on Thursday revealed Bryant has a fracture in his lateral tibial plateau - the top of his shinbone, near his knee.

Bryant made his season debut with the Lakers on Dec 8 after nearly eight months away while recovering from a torn Achilles tendon.
