New England coach Bill Belichick doesn't often provide information about injured players, but a source told the Boston Herald that running back Sammy Morris will miss Sunday's game against Miami and could be out a month. The source told the newspaper that Morris injured the bone connecting the sternum to the clavicle. The running back left Texas Stadium in a sling and reportedly is in excruciating pain. Morris, a former Dolphin, made his third straight start in place of Laurence Maroney, who is out with a groin injury. In the first two games, he passed 100 yards rushing and has three touchdown runs this year.
