Coach Jason Garrett made the decision to hold out Murray after not seeing enough in three limited practices last week.
"I thought I was going to go, but it was his choice to rest me one more week, but he made a good call," said Murray, who suffered a sprained MCL in his left knee on Oct. 13 versus the Washington Redskins. "It was best for this team and for myself."
Murray was able to take part in his first full practice on Wednesday since getting hurt, but he is not sure if Garrett will give him the go-ahead for Sunday's game against the Minnesota Vikings. He has missed the past two games, the 10th and 11th missed games of his three-year career.
"You get your hopes up and it's a little frustrating, but you got to come to the conclusion it's a long season and whatever they're doing is best for me and best for this team," Murray said. "But it was tough watching on the sidelines, but he knows what's best for our team."
Murray said he is not wearing a brace in practice and it will not take him long to get back up to speed.
"I only missed one week, as opposed to last year it was a little harder after missing so many games," Murray said of his six-game absence with a foot injury. "But just missing one week, I feel like I haven't been off."
In his first game back last year, Murray ran 23 times for 83 yards and a touchdown against the Philadelphia Eagles. The Cowboys have rushed for 136 yards in the two games without Murray, who was on pace for his best season with 428 yards on 91 carries before getting hurt.
"I don't know if I can put a percentage on [the knee], but feeling better, feeling like I can contribute at a high level and help this team win," Murray said.
