8:51pm: Nick Piecoro of the Arizona Republic has the financial details; the contract is worth $3.05MM.
8:35pm: MLB.com's Steve Gilbert reports that the Diamondbacks have agreed to a one-year contract with outfielder Conor Jackson.
An arbitration hearing was scheduled for Wednesday, so the deal was struck just in time. Financial terms are not yet available, but the sides probably settled near the midpoint of the numbers that were filed at the end of January. The Diamondbacks submitted a $2.45MM bid and Jackson's representatives countered with a request for $3.65MM.
GM Josh Byrnes has not required an arbitration hearing in his time with the Diamondbacks.
