新近加盟布法罗比尔的防守绊锋达尔文·沃克（Darwin Walker）表示，在收到新合同之前将不会到球队报道。

　　比尔队今年3月用线卫塔高·斯派克（Takeo Spikes）从费城老鹰换来了沃克。而现在沃克则表示，在新合约签订之前他将不会前往布法罗。尽管沃克目前的合同还有两年才到期，但他正在试图与老鹰队就新合同展开协商。

　　沃克的经纪人艾伯特·厄拜（Albert Irby）表示比尔队在完成交易时非常清楚沃克的合同状况。“是的，他是有约在身，那份合同也被卖给了布法罗队。但是在交易时布法罗队明白我们希望签订一份新合同。”厄拜在接受美联社采访时表示，“他们在清楚这件事将会发生的情况下完成了交易。”

　　厄拜同时表示已经与比尔队进行了讨论，并且希望在七月下旬的训练营开始前与球队达成协议。比尔队还没有对此事发表评论。

　　沃克是一名拥有七年职业经验的资深球员，此前比尔队与老鹰队关于沃克的谈判曾一度陷入僵局。双方最终达成协议，老鹰队随之签下了身为自由球员的防守绊锋蒙蒂·里格（Montae Reagor）以取代沃克的位置。

　　沃克上赛季在15场比赛中首发，并且完成了36次擒抱和15次擒杀。在NFC季后赛第二轮老鹰24-27负于圣徒的比赛中，他又贡献了两次擒杀。沃克无疑是加强比尔队防守实力的最佳人选。

　　作为交易的一部分，比尔队将在明年的选秀中获得一个有条件的名额，届时该队将完成有关替补四分卫凯利·霍尔库姆（Kelly Holcomb）的交易。

　　BUFFALO， N.Y. （May 10， 2007） —— Newly acquired defensive tackle Darwin Walker won＇t report to the Buffalo Bills until he receives a contract extension.

　　Acquired in a trade in March that sent linebacker Takeo Spikes to Philadelphia， Walker said he hasn＇t visited Buffalo yet and will not report until a new deal is completed. Walker has two years left on his existing contract， but was attempting to negotiate a new deal with the Eagles.

　　Walker＇s agent， Albert Irby， said the Bills were aware of his client＇s contract status when they made the trade.

　　"Yes， he＇s under contract， and that contract was traded to Buffalo. But it was traded to Buffalo with the understanding that we wanted a new deal，" Irby told The Associated Press. "They made the trade knowing that this had to happen." Irby said he＇s had discussions with the Bills， and hopes an agreement can be reached prior to the start of training camp in late July.

　　The Bills did not immediately return messages left by the AP.

　　Walker is a seven-year NFL veteran， who proved expendable in Philadelphia after he and the Eagles reached an impasse in contract talks. The two sides then agreed to a trade， which also led the Eagles to land Walker＇s replacement by signing defensive tackle Montae Reagor in free agency.

　　Walker is a penetrating tackle that fits the mold of a Bills defensive front that is being asked to do more than just stop the run.

　　He＇s coming off a solid season in which he had 36 tackles and six sacks in 15 starts， and added two more sacks in a 27-24 loss to New Orleans in an NFC second-round playoff game.

　　As part of the trade， the Bills also acquired a conditional pick in next year＇s draft， while dealing journeyman backup quarterback Kelly Holcomb.
