Kevin Hart is on a long road to recovery after injuring his spine in a serious single car crash in Calabasas, California.

A surgeon fused the 40-year-old comedian's back after his spine was fractured in three places, and now Hart will be transferred to a rehabilitation facility where he will remain for 4 months.

Hart's camp originally said he did not injure his spinal cord, but sources say Hart did suffer an injury to his spinal cord that affects his mobility from the waist down.

Hart's family, including his wife Eniko and children will take active part in his physical therapy.

A source tells The Blast Hart needs at least 4 months of physical therapy before he will be able to walk onto a movie set.

Sources close to the situation tell The Blast Hart needs intensive physical therapy at a rehab facility where he can be monitored closely.

The Jumanji star is reportedly in extreme pain and is still dependent on potent painkillers.

According to The Blast, as soon as doctors and physical therapists determine Hart is stable enough to do the physical therapy in an outpatient environment, he will be released from the rehab facility.

Hart routinely updated his social media with photos and videos that showed him working out or running in marathons.

"It helps that he was physically in such great shape," one source told The Blast.
