The Arizona Cardinals will be without one of their top deep threats for Sunday's game against the Detroit Lions.

Kirk had a groin issue in the team's win over the Washington Football Team in Week 2, and he did not practice on Thursday.

Apparently, the issue is severe enough to keep him out in Week 3 (via Darren Urban of Cardinals' official site).

Kirk had struggled to get in a good rhythm to start the year.

The 23-year-old was shut out and had just one target against the San Francisco 49ers in Week 1. Kirk did make a pair of big plays against Washington, notching two receptions for 57 yards. But he was also forced to miss some action with the groin injury, and will now be sidelined against the Lions.

Arizona's offense has flourished to start the season.

Star quarterback and reigning NFL Offensive Rookie of the Year Kyler Murray has been explosive using both his arm and his legs. Murray has thrown for 516 yards while also rushing for a team-high 158 rushing yards and three scores.

Murray has certainly benefited from the arrival of DeAndre Hopkins.

The All-Pro receiver has had a massive start to his Cardinals career, racking up 22 catches for 219 yards and a touchdown in his first two games. Hopkins also took the blame for one of Murray's interceptions after apparently running the wrong route, which was greatly appreciated by the young quarterback.

Arizona is looking to challenge the injury-riddled San Francisco 49ers for the NFC West crown. The Cardinals will hope Murray and the offense can keep rolling without Kirk as they prepare to take on the Lions.
