BOSTON (CBS) — The Arizona Cardinals will be visiting Foxboro this weekend. They may not have their star young quarterback.

Kyler Murray was a limited participant in Tuesday’s practice, and on Wednesday morning, Cardinals head coach Kliff Kingsbury said he’s not yet sure if Murray will be ready to go by Sunday.

“We’re going to see [Wednesday] how he progresses,” Kingsbury said on a conference call with New England reporters. “I feel positive, but we want to make sure that he’s feeling able to play his game and play at a high level and do the things that he feels comfortable doing out there. So, we’ll see how the day goes and kind of take it from there.”

Murray, 23, suffered a shoulder injury during Sunday’s loss in Seattle. He played through the discomfort, throwing for 269 yards and a pair of touchdowns, but he had to apply heat to the injured area every time he went to the sidelines.

Murray noted on Tuesday that he feels fine, but Kingsbury noted that some adjustments needed to be made with his practice workload.

The status of the No. 1 overall pick of the 2019 draft figures to be significant. The Cardinals, at 6-4, are currently in position for the third wild card spot in the NFC, but a loss would bring them closer to the 5-5 Bears and three teams — Minnesota, Detroit, San Francisco — that are currently at 4-6.

Rookie Chris Streveler and Brett Hundley are the Cardinals’ backup QBs, in the event that Murray can’t play.

UPDATE: Murray was as limited participant in Wednesday’s practice.
