"R.A. Dickey will go forward with his charitable plan to ascend Mount Kilimanjaro next week, despite the Mets' objections, multiple sources said Tuesday.

A person close to Dickey confirmed the Mets sent a "procedural" letter to agent Bo McKinniss "just to cover themselves legally" over the summer, when the knuckleballer first began publicly discussing the excursion.

Dickey is scheduled to earn $4.5 million in 2012 in the second year of a two-year, $7.8 million deal. The letter stated the Mets reserve the right to void Dickey's contract if he is injured as a result of the climb."
