Kareem Abdul-Jabbar Hospitalized After Falling and Breaking His Hip

Kareem Abdul-Jabbar took a nasty spill at a concert in Los Angeles -- and the NBA legend ended up in the hospital with a broken hip, TMZ has learned.

His rep, Deborah Morales, tells us ... Kareem was attending the show Friday night -- but it was unclear who was performing and where. Anyway, the former Lakers star center accidentally fell to the floor, shattering his hip.

Paramedics quickly responded and transported Kareem to the hospital for treatment.  His condition was not disclosed.

Morales said Kareem was "deeply appreciative" of the support he received from the Los Angeles Fire Department on site and the "amazing medical team and doctors at UCLA Hospital who are taking great care of (him)."

Based on what his rep is saying, it sounds like Kareem is going to be OK.
