Kliff Kingsbury said on Monday that he is hopeful that Kyler Murray will play on Sunday after missing time with an ankle injury, but that he won't fully commit to him playing until he sees him moving around in practice this week. (Darren Urban on Twitter)
This is obviously not what fantasy managers want to hear, but there's no reason to panic about it yet, and Kingsbury is likely just being cautious. Murray wasn't even ruled out until gameday in either of the last two weeks prior to the bye, and has now had several weeks to recover from the ankle injury. Monitor the practice reports, of course, but as of now, plan on Murray suiting up against the Bears.
