Cooper Kupp's hamstring isn't cooperating at the wrong time.
The receiver experienced a "setback" in his road back from a hamstring injury, Rams coach Sean McVay told reporters on Thursday, adding Kupp suffered a "muscle strain." Kupp is considered day to day, per McVay.
Thursday's news is certainly concerning for the Rams, who are, as McVay said, "obviously a much better team when he's available."
The nature of the injury is doubly worrying, too, as hamstrings tend to become nagging issues if not treated with caution.
Los Angeles sustained a significant number of injuries in 2022, contributing to their downfall from reigning champion to also-ran. Kupp was among those, seeing his season cut short after just nine games. And when Kupp departed, the Rams' offense took a sharp nosedive.
Los Angeles won't want to start another season without its best weapon and former Super Bowl MVP. With a little over a week left to go before it begins, the Rams will have to closely monitor Kupp with the hopes he can return fairly quickly without risk of it becoming a frequent issue.
