Coulombe's contract was restructured after the Red Sox discovered issues in the pitcher's physical examination, Chris Cotillo of MassLive.com reports.
The overall value of the deal remains the same, but the guaranteed portion was reduced to $1 million. Coulombe can achieve another $2 million in performance and active roster bonuses throughout the season. Both parties in the contract renegotiation -- Boston chief baseball officer Craig Breslow and Coulombe's agent -- declined comment when asked about the situation. There have been no signs of limitation thus far. Coulombe threw a live batting practice Monday and is scheduled for his Grapefruit League debut Thursday.
