He's improving after that 12-hour surgery in March in New York City, but Hall of Fame quarterback Jim Kelly will require more follow-up surgery next month.  His wife, Jill, posted an update on his progress yesterday on Instagram.

She revealed that Kelly visited New York City on Wednesday for a check-up and strategy meeting and that doctors were impressed with the progress he's made since the surgery in March to remove cancer from his upper jaw.  Part of the follow-up surgery next month will involve placing implants in his upper jaw.

Update... Went to NYC yesterday for a checkup and moving forward, strategy meeting. The doctors were very impressed with how much Jim has healed since he’s been home. Praise God! The plan at this point is that he will have surgery in mid-June to lesson the “skin flap” bulk in his mouth, as well as put implants into his upper jaw. And then there will be more healing and waiting and then another surgery and possibly upper teeth sometime in September. All of this of course is wrapped up in the perfect plan and purposes of God...who knows all, is sovereign over all, and graciously orchestrates the details of our lives, holding everything together, and working everything together for good. None of us know what tomorrow holds...but we can choose to trust the ONE who holds tomorrow. Thank you for loving us and praying us through all of this.

After the June surgery "there will be more healing and waiting and then another surgery and possibly upper teeth sometime in September."  Jill Kelly gave thanks for all the love and prayers throughout the ordeal.

Jim Kelly made a surprise appearance during Bills rookie mini-camp last week and spent some time talking with first round draft choice quarterback Josh Allen.  Kelly came away impressed with the rookie quarterback.
