"When I signed on that dotted line, I knew I was going to be here for a long time," Murray said Thursday. "I'm committed to winning a lot of games here. We're tied for first place in our division. We've got a chance to do some special things here."
Murray also explained that speaking with Lurie isn't a new development.
"That's not the first time I've sat next to Jeffrey," Murray said. "It's not the first time I've spoken to him. I was sitting right next to him. I can't speak to my boss?"
ESPN's Ed Werder reported Monday that Murray was upset by his lack of carries in Sunday's 35-28 win over the New England Patriots. Eagles head coach Chip Kelly said Murray was "frustrated."
On Thursday, Murray said the report was "very surprising. I can't control it. I don't know how it got out there. It's just communication with my boss, that I work for. I think it was definitely made a lot bigger than what it really is."
Murray was on the field for only 14 of the Eagles' 61 offensive plays. He carried the ball eight times for 24 yards. In his 10 prior games this season, Murray averaged 53.8 percent of the Eagles' offensive plays.
"I wouldn't say I was disappointed," Murray said. "We won the game, so I was happy with that. Every player wants an opportunity to contribute to the team -- especially me as a competitor.
"Obviously, it's hard. I've never been in that situation before. You've got to deal with it. Every guy in this locker room wants the ball. It's not just me. Everyone loves the football. The biggest thing for me is how I'm going to contribute to this team. I feel like I can be a big piece of that. Obviously, we won the game. I'm extremely happy about that. But you always want to contribute, whether it's passing the ball, blocking, catching, whatever the case may be."

Chip Kelly has running back problems
ESPN Eagles reporter Phil Sheridan says RB DeMarco Murray picked a bad week to talk to owner Jeffrey Lurie about frustrations. With LeSean McCoy's return to Philadelphia, if Eagles fans boo one of those backs, it might not be McCoy.
