The Lakers have hit the road for a three-game trip, but Pau Gasol remains in Los Angeles trying to recover from a groin injury.

Gasol was declared out at least a week on Saturday after aggravating the injury in a Friday night loss to the Charlotte Bobcats.

On Monday night, Gasol posted a photo on Instagram, revealing he underwent platelet-rich plasma therapy to help accelerate the healing process.

The treatment involves drawing some of Gasol's own blood. The platelets, which promote healing, are then filtered to concentrate them, then injected directly into the problem area.
