The Patriots have released tight ends Carson Butler and Rob Myers, according to a league source. The 6-foot-4, 255-pound Butler, a 23-year-old out of Michigan, was signed by the Patriots on Aug. 2. Myers, 24, is a 6-foot-4, 240-pounder out of Utah State who was signed to New England's practice squad last November. Both players have practice squad eligibility, and could end up there when the practice squad is assembled this weekend. The news on both was first reported by ESPN.
