It’s unclear what the market might be."Alex Clancy, host of the LockedOnAZCards podcast, echoed a similar sentiment.Alex Clancy @ClancysCornerLINKIf Kyler Murray is healthy, and Jacoby Brissett starts Monday night, the Arizona Cardinals should 100% try to move Kyler Murray before the trade deadline. Not saying K1 is healthy. I’m saying IF that’s the case, his trade value will never be higher than right now."If Kyler Murray is healthy, and Jacoby Brissett starts Monday night, the Arizona Cardinals should 100% try to move Kyler Murray before the trade deadline.

He was immediately named as the team's QB1, helping them to a 5-10-1 record and tallying 3,722 yards and 20 TDs. In July 2022, the quarterback agreed to a five-year contract extension worth $230.5 million.Murray injured his foot during their 22-21 loss to the Tennessee Titans in Week 5. This sidelined him for two games, while Brissett took over as his replacement. He is expected to return to the field during the team's Week 9 game against the Dallas Cowboys as they attempt to end their five-game losing streak.Cardinals WR Marvin Harrison Jr. opens up about Kyler Murray's contribution to the offenseOn Thursday, Cardinals wide receiver Marvin Harrison Jr. shared his thoughts on Kyler Murray and the impact of his presence on the offense, amid reports of his return on Monday."Yeah obviously, he has the running ability to extend those plays," Harrison said. "They definitely puts a factor of defense especially when a quarterback runs, that's a threat."They were reading one person, that takes one guy out on the run a little bit. So, now we've seen in the past games he can extend the play like no other quarterback. So if he plays, he brings that to the table.Murray participated in Thursday's practice in a limited fashion. Both he and Jacoby Brissett took reps with the team's starting pass catchers. Coach Jonathan Gannon just said "yeah" when questioned whether the two-time Pro Bowler will play on Monday.The Cardinals vs Cowboys showdown kicks off at 8:15 p.m. ET and will be broadcast on ESPN, AB, and NFL+.
