Smith suffered a gruesome compound fracture against the Texans in which a bone was protruding through his skin. He underwent surgery and was expected to need six to eight months for recovery, but then suffered through infection after multiple surgeries.
On Sunday, the 34-year-old QB was finally released from the hospital.
Smith's wife Elizabeth sent out a picture on Instagram of her husband in front of the Christmas tree.
"This last month has been a difficult ride," she wrote. "Our family is beyond happy to have this man with us and home. This experience has given us great perspective and gratitude for all the people and blessings in our lives."
