The Dolphins are not concerned about Ted Ginn Jr.'s midfoot sprain that has nagged him since January and will keep him out of the team's minicamp. ESPN.com reported Sunday that Ginn Jr. would be in a boot for six weeks and then require a six-week rehabilitation.

The Dolphins aren't done trying to dismantle their roster from last season, with a source saying today that wide receiver Marty Booker is on the trading block. It's unknown what compensation the Dolphins are seeking for Booker, an eight-year veteran who was acquired in 2004 along with a third-round draft choice from Chicago for defensive end Adewale Ogunleye. The Dolphins have tried to accumulate draft picks by trading other veterans and have accumulated 10 selections heading into this weekend's draft. Booker could potentially figure into the trade talks being held between the Dolphins and Kansas City for Chiefs quarterback Trent Green. Shopping Booker also may indicate the Dolphins have targeted Ohio State wide receiver Ted Ginn Jr. with the draft's No. 9 overall pick. The Dolphins already have jettisoned two of their top four leaders in receptions from last season by releasing tight end Randy McMichael and trading wideout Wes Welker to New England for second- and seventh-round picks.

The Dolphins should complete a trade for Kansas City quarterback Trent Green before the end of this weekend's NFL Draft, a source said Friday. The negotiations, which began in late February, most likely will conclude Sunday, the source said. The developments signal a change in Kansas City's steadfast demand for a second-round pick in return for the 36-year-old, two-time Pro Bowl quarterback.

Quarterback Daunte Culpepper now realizes the Dolphins are expected to soon trade or release him and said in a statement Thursday he would like to be told of the team's intentions. ''Since I am a player/agent and there are discussions about my career taking place, I expect to be included in those discussions sooner rather than later,'' Culpepper said in a statement e-mailed to various media outlets. 'As it pertains to being traded or released, I don't get to make that call so I will await the Dolphins' decision.''

The Dolphins on Wednesday re-signed linebacker Donnie Spragan to a one-year contract. Financial terms were not disclosed.

The Miami Dolphins fired running backs coach Bobby Williams on Friday. The Dolphins said they would begin to search for a replacement immediately, but did not disclose why they fired Williams three months after new coach Cam Cameron took over for the departed Nick Saban. "We want to thank Bobby for his time with the Dolphins and wish him nothing but the best in the future," Cameron said.

The Dolphins hosted a couple of top draft prospects Thursday: Ohio State receiver/returner Ted Ginn Jr., and according to a source, Penn State tackle Levi Brown. Both are considered the draft's second-best players at their positions and would provide depth at two of the Dolphins' thinnest spots.

The Dolphins declined to match the five-year, $5.9 million offer sheet that punter Donnie Jones signed last week with St. Louis. The Dolphins will receive the Rams' seventh-round draft choice (225th overall) and have a total of 10 picks.

Ricky Williams is six days from being eligible for reinstatement to the NFL, but the suspended running back may have to wait until after the draft April 28-29 before being able to officially rejoin the Dolphins. Williams was banned from the NFL on April 25, 2006 after losing an appeal of a fourth failed drug test. Agent Leigh Steinberg said Wednesday that Williams has sent a letter asking for reinstatement to NFL Commissioner Roger Goodell

Miami signed center Johnathan Ingram and running back Ray Perkins on Monday. Ingram, 26, joined Kansas City as an undrafted free agent in 2003 and has appeared in four games with the Chiefs. Perkins, 24, went to camp with San Diego as an undrafted free agent in 2005 and spent time over the past two seasons on the Chargers' practice squad.
