"I got hurt when I got tackled a couple of games ago," said Murphy. "I had been running hard and I got hurt.
"The doctor hasn't released me yet, so I haven't been able to play. It's been frustrating, but I am still with my team and I am out there on the sidelines trying to help the other running backs."
Murphy reports that not being able to be on the field to contribute with his fellow seniors.
"Being away has made me love the game more," said Murphy. "I guess I could let it get me down, but I am not doing that. I am still trying to learn and just be around the team.
"All of this has just makes me want to play that much more."
Murphy reports that his commitment to Mississippi State remains firm and that he plans to be back on campus later this week.
"I was just talking with Coach (Greg) Knox a little while ago," said Murphy. "I am going down there this weekend to see them play Texas A&M. Me and my kicker, Logan Tyler, who is also getting recruited by Mississippi State are planning to get down there for the game."
After seeing the Bulldogs run over, around and through the Tigers of LSU, Murphy is fired up about the future.
"It was so exciting seeing them beat LSU," said Murphy. "Josh (Robinson) and Dak (Prescott) were both hitting the hole hard and just doing all of the things you need to do to be successful.
"I think it's going to be a good game this weekend, but I think Texas A&M is going to have a lot of trouble stopping our running game.
"I expect an explosive offense and a focused defense and I think we're going to win the game."
