A new contract for Trent Green is holding up a possible deal that would send the former Pro Bowl quarterback from Kansas City to the Miami Dolphins, sources said Wednesday. The Dolphins, like the Chiefs, want Green to take a major pay cut from the $7.2, $7.7 and $9.2 million the 36-year-old veteran is due over the next three seasons, the final three years on his current contract. Miami doesn't want to pay Green, who will turn 37 in July, much more than the NFL veteran's minimum, which is $820,000 in 2007. To acquire Green, the Dolphins likely would trade the second seventh-round draft pick they obtained from New England for receiver Wes Welker. But, sources said, the sticking point for the Green deal is money.
