Los Angeles Rams

Los Angeles Rams wide receiver Puka Nacua (knee) will undergo testing on his knee Monday afternoon after leaving Sunday night's game against the Detroit Lions. According to Ian Rapoport, the star receiver is scheduled to get some testing done after injuring the same knee that he tweaked during the preseason. Nacua was able to come back for one play in Sunday night's game, but ultimately left again and did not return. There still hasn't been any word or speculation on what's wrong with his knee, so these tests should provide a clear picture of the extent of the injury. If he'll need to miss some time, Tyler Johnson did a good job filling in against the Lions, while Tutu Atwell and Jordan Whittington may also see some more snaps.

Los Angeles Rams rookie kicker Joshua Karty did not appear intimidated by a large crowd and raucous road atmosphere in his first NFL game at the Lions on Sunday night. The Stanford rookie made both of his field goals, including a 41-yarder, and buried both of his extra-point attempts. It was a good sign that Karty could be a viable fantasy kicker this season. He looked smooth and unfazed in both of his field goal attempts, albeit in a controlled indoor environment at Ford Field. There could be some growing pains along the way for Karty but he looks like an NFL-ready kicker as the Rams probably expected after selecting him with a sixth-round pick in this year's draft. With other solid kicker options out there, fantasy managers can take a bit of a wait-and-see approach with Karty, but he could end up being a useful fantasy option this season.

Los Angeles Rams wide receiver Tyler Johnson took advantage of Puka Nacua (knee) leaving the game early with some big catches against the Lions on Sunday night. Johnson caught five of his seven targets for 79 yards, including a 63-yard catch and run when he stopped on a dime and turned a short pass into a long gain. The Minnesota Golden Gophers product stepped into the void opposite star receiver Cooper Kupp when Nacua left the contest. With Nacua set to undergo testing Monday on his right knee, Johnson could be a popular waiver-wire addition should Nacua be forced to miss any time. Demarcus Robinson also saw seven targets in the game but Johnson looked like the greater big-play threat.

Los Angeles Rams wide receiver Cooper Kupp turned back the clock a bit with a dominant game in the team's overtime loss at the Lions on Sunday night. With Puka Nacua (knee) forced to exit the game, Kupp was targeted early and often by Matthew Stafford. He saw a ridiculous 21 targets and caught 14 passes for 110 yards and a touchdown. Kupp worked the short field relentlessly using pre-snap motion to perfection on a nine-yard touchdown catch. A healthy Kupp is still one of the most dangerous receivers in the NFL and his connection with Stafford along with the way Sean McVay and the Rams' coaching staff schemes him up, is a thing of beauty at times. Nacua came back for one play after being injured but was forced to leave the game and will undergo testing on his right knee on Monday. With his health in question, Kupp's status elevates even more. Kupp is a no-doubt WR1 while healthy and could be one of the best values of this year's fantasy drafts if his target share keeps up at this pace.

Los Angeles Rams running back Kyren Williams dominated the workload out of the Rams' backfield against the Lions on Sunday night and found the end zone. Overall, Williams recorded 18 carries for 50 yards and a rushing score and caught all three of his targets for four yards. The most important note, however, was that Williams saw 67 snaps in the backfield compared to just seven for Ronnie Rivers and none from Blake Corum. That works out to 91 percent of snaps for the Notre Dame product, who was expected to see some of his workload cut into by Corum, the rookie out of Michigan. Against a tough Lions run defense, Williams struggled to 2.78 yards per carry, but the outlook is rosy for the talented and versatile running back because of the extremely large snap-share. While it is natural to think Corum will become more involved as the weeks go on, if Williams dominates touches like this he should be in line for some huge fantasy weeks.
