DECEMBER 15: At least a one-game absence is likely in store for Adams. He’s considered week-to-week after aggravating his previous hamstring injury, according to Ian Rapoport of NFL.com.
DECEMBER 14: Early on in the season, Rams wide receiver Davante Adams sustained a mild hamstring strain. While the injury put him on the practice injury report, he didn’t miss any time because of it. In today’s big win over the Lions, though, Adams seemed to aggravate the injury into a higher severity. 
For what it’s worth, per Sarah Barshop of ESPN, Adams is “optimistic” about the injury. He played through it in the early weeks of the season, and though it’s resurfaced over the last few weeks, limiting him in practice, Adams has been able to tough it out and play his way through it. Trainers do sometimes have to call out injuries players refuse to respect and pay heed to, but Adams know his body better than anybody else.
That being said, according to ESPN’s Adam Schefter, head coach Sean McVay told reporters that Adams’ hamstring injury “didn’t look good,” communicating that the veteran wideout’s status could be in doubt for Week 16. The Rams play on a short week of rest next week with a Thursday night road trip to Seattle next on the docket. Hamstring injuries don’t typically subside quickly after aggravation, so McVay’s concern is well warranted.
So far this season, Adams has been one half of a two-headed monster in the Rams passing game across from Puka Nacua. Coming into the week, both players boasted triple-digit targets while the next most-targeted player was running back Kyren Williams with 35. After taking out Williams and tight ends, second-year receivers Jordan Whittington (23) and Xavier Smith (14) and rookie seventh-rounder Konata Mumpfield (8) made up the rest of the receivers target share entering the week. The team did return Tutu Atwell from injured reserve this weekend, and he may stand a better chance a dipping into the target share.
Ultimately, per ESPN’s Lindsey Thiry, McVay concluded vaguely, “We will see what’s going on with Davante.” An optimistic Adams and skeptical McVay will navigate the short week ahead of them before making any official decisions for Thursday.
