Answer based on context:

Still searching for their first win of the year, the Dolphins returned home for a Week 7 AFC East duel with the undefeated New England Patriots.  In the first quarter, Miami's struggles continued as Patriots QB Tom Brady completed a 30-yard TD pass to WR Dont&#233; Stallworth and a 2-yard TD pass to TE Kyle Brady.  In the second quarter, the Dolphins got their only score of the half with QB Cleo Lemon getting a 4-yard TD run.  Afterwards, New England continued its pounding with CB Willie Andrews returning a kickoff 77 yards for a touchdown, along with Brady and WR Randy Moss hooking up with each other on a 35-yard and a 50-yard TD pass.  The Patriots would end the half with Brady hooking up with WR Wes Welker on a 14-yard TD pass. After a scoreless third quarter, Miami tried to make a comeback in the fourth quarter.  It began with RB Patrick Cobbs getting a 1-yard TD run, along with DE Jason Taylor returning an interception 36 yards for a touchdown.  However, New England made sure that they sealed their victory with Brady hooking up with Welker again on a 16-yard TD pass.  Afterwards, the 'Fins ended the game with RB Jesse Chatman getting a 7-yard TD run. With the loss, not only did the Dolphins fall to 0-7 for the first time in franchise history, but they also lost RB Ronnie Brown for the year, as he tore his ACL in the third quarter while trying to stop an interception return.
