Sensing Boss might not be ready for the opener, Oakland kept four tight ends on its 53-man roster, though none of the remaining three have much experience.
"It's a different atmosphere so everyone's kind of jacked up a little bit," Myers said. "I'm confident in myself and my abilities. I just feel like my play has been consistent. I think that's what every football player tries to do."
Murphy, the team's fourth-round draft pick in 2009, underwent surgery for a sports hernia early in training camp and told reporters he might not return until Oakland's home opener against the New York Jets on Sept. 25.
"That's what we're shooting for," said Murphy, who led all Raiders wide receivers with 41 catches last season. "I've been jogging and doing some light sprints. Just been trying to get back into the groove of things. It's coming along real well."
