How are your putting stats?....with 6 weeks of putting practice you could shave major strokes off your game. Practice short putting drills like Phil Mick and you could become deadly accurate from 3-5 feet.
Practice your :
Grip
Hinging
Roll procedure
Wristcock
Basic motion
Flying wedges
Extensor action
You can do all the above sat on a stool.If you can stand get one of those foam balls and chip against a wall-if you are accurate the ball comes back!
Good luck and a speedy recovery
