Murray didn't attend the Cardinals' organized team activities last week.
Coach Kliff Kingsbury said he didn't know if Murray would be in attendance for the rest of this week's organized team activities.
"It was good to have him. We've been in constant communication, so we'll just kind of take it one day at a time," Kingsbury said on Wednesday.
Murray didn't talk with reporters on Wednesday.
The Cardinals' mandatory minicamp is scheduled for June 14-16 and Kingsbury said last week that he expected Murray to be in attendance.
The Cardinals exercised the fifth-year option on Murray's contract last month, guaranteeing him a salary of about $29 million in 2023. Murray, however, has been seeking a long-term contract extension. In February, Murray's agent, Erik Burkhardt, posted a letter on Twitter that explained how a detailed contract proposal was sent to the team.
Last month, general manager Steve Keim said there was "zero chance" he would trade Murray and noted that other third-year quarterbacks who have signed extensions, such as Patrick Mahomes and Josh Allen, received their deals in the summer.
Murray himself tweeted in April, "I wanna win Super Bowls with the Cardinals, AZ is home," in response to comments by former Cardinals Patrick Peterson and Chase Edmonds on the "All Things Covered" podcast that they believed Murray would seek an exit from the franchise because of the team's culture.
Murray, the 2019 Offensive Rookie of the Year and a two-time Pro Bowl selection, led the Cardinals to the playoffs last season for the first time since 2015.
