"It's been a long time since I put cleats on," Murray told reporters. "I've been running around. The cleats were pretty new.
Murray limped to the podium for his post-practice news conference. Cardinals coach Kliff Kingsbury said the team would try to get Murray new cleats for Saturday's practice.
Murray was the No. 1 overall pick in the 2019 NFL Draft. Arizona opened its rookie minicamp Friday and will practice throughout the weekend.
"It was good finally touching the field again," Murray said. "A lot of this process has just been a lot of talk and evaluation and stuff like that. Just to actually be able to play football again, get out here with the guys and do what you love, it was fun."
