Kyler Murray was eligible to return to play on Monday, but the quarterback won't return to practice this week.
Coach Jonathan Gannon said Murray's 21-day practice window remains closed with the quarterback on Injured Reserve.
"(He's) not quite there yet," Gannon said.
Murray has now missed seven games after hurting his foot Week 5 against the Titans. His minimum of four weeks on IR ended after the Cardinals' game in Tampa on Sunday.
Later on his weekly interview on Arizona Sports, Gannon was asked if Murray was going to be able to return this season. "I don't know," he said. "I'm hoping." He emphasized he would have no concern playing Murray in a game when and if he was able to return.
Asked if Murray could eventually have surgery, Gannon said he did not know if that might be the case.
Wide receiver Marvin Harrison Jr. will be further evaluated on his heel injury and see where he is "later in the week." Harrison had six catches in his return from appendix surgery but was limited to 37 snaps with the new injury. Gannon said cornerback Max Melton has a similar injury.
Quarterback Jacoby Brissett has averaged 313 yards passing in his seven starts while Murray has been out, with 13 touchdown passes and four interceptions, while being sacked 26 times. Gannon said Murray has improved with his injury.
"He's working every day," Gannon said. "I know he wants to be out there. It's just unfortunate right now.
"When your health is preventing you from doing that it can get frustrating."
Brissett remains the QB with the NFC West-leading Rams visiting on Sunday. The Cardinals, at 3-9, were officially eliminated from the postseason after the loss to the Buccaneers.
"I'm not pleased where we are but it's our path right now," Gannon said. "Being eliminated, that sucks when you think about it. But I'm not going to let that affect, when I turn on the tape, my process to do my job at a high level. "
Trey McBride -- who is leading all NFL tight ends in Pro Bowl votes -- made clear that even with no postseason to chase, he had no problem finding motivation for the final five games.
"You're in the National Football League. This is something I've dreamed of my whole life," McBride said. "If you were to tell me I wouldn't care about a football game, whether we are 10-0 or 0-10, like, I'm going to go out and play and give everything I have. I owe it to my teammates, I owe it to the fans, I owe it to the organization, I owe it to everybody to put my best foot forward to be the best version of me I can be. I expect that from all my teammates as well.
"I hope they expect that from me because you get to play this game and compete against the best players in the world. To have another opportunity this week to do that, there's nothing like it. I'm going to go out there and keep fighting and give everything I have until I can't."
