Former Panthers QB Chris Weinke, who underwent spinal fusion surgery similar to Peyton Manning's, regained 100 percent of his arm strength after seven months.
Comparing his injury to Manning's, Weinke said: "In terms of the similarities between the two, the fusion and the nerve regeneration are exactly the same." Weinke couldn't grip a ball at first and didn't throw "with purpose" for five months. Manning was throwing in December, three months after his surgery, leaving him ahead of Weinke's pace. Although he had to rebuild arm strength from "ground zero," Weinke actually gained velocity post-surgery due to a focus on the "little muscles" in his upper arm.
