At the time the offer was withdrawn, neither Webb nor the team indicated the reason.
However, the Arizona Republic, via Foxsports.com, is reporting that the team withdrew the offer due to the inability to secure insurance. The insurance company "expressed concerns about the right-hander's arm."
Diamondbacks GM Josh Byrnes wouldn't discuss the report with the Arizona Republic.
"When it comes to details pertaining to negotiations, it's not something I want to talk about on or off the record."
"In the short term," Byrnes continued, "we will continue to monitor Brandon's (health) status and I believe he will be back on the mound shortly. We'll keep everyone notified of that, but talking about his contract or any negotiations is not something we want to talk about."
Webb, who will miss his Saturday start due to stiffness in his shoulder, is under contract for this year and the team has an option for 2010.
