The Canadian hopes to be ready for Augusta National.
Weir had a tendon injury in his right elbow last year and tried to play through it until deciding to take off the final four months of the season. He says he is skipping Bay Hill because he does not want to make the same mistake twice.
He says by having the cyst drained now, it will be able to heal properly and allow him to play the Masters and the rest of the year.
Weir failed to make enough money the first two months to retain his card. He is playing the rest of the year on his status as a past PGA Tour winner and through sponsor invitations.
