Rams star WR Cooper Kupp suffered a high-ankle sprain in LA’s loss on Sunday, and he’ll spend the next week or so in a cast helping the swelling calm down, sources said.

The team did not place him on Injured Reserve, as there is still a chance he’s ready within four weeks.

A little bit of good news bad news here, as Kupp may not miss more than four games, but it still seems like it will be significant time. As it stands, Robinson is the most experienced option and will be the most likely option to lead the team in routes, with Johnson closely behind.

If you missed out on them through waiver runs and still want a piece of this offense, Whittington is the wild card, and should be targeted in deeper leagues.

Rams head coach Sean McVay said that wide receiver Cooper Kupp and left guard Jonah Jackson are both set to miss extended time after suffering injuries in Sunday’s loss to the Cardinals. Kupp hurt his ankle and Jackson aggravated a shoulder injury.

McVay also confirmed that safety John Johnson will miss multiple weeks with a shoulder injury. He called all three players candidates for injured reserve.

With Nacua already on IR, the Rams offense is taking another hit with the loss of Kupp. Robinson and Johnson could take over as the team's top two, but those of you in the dynasty community may be high on Whittington, who has drawn comparisons to Nacua. Any of the three are worth picking up, and could get significant time over the next month at least.

Nacua is still going through additional testing, according to Schefter. He is expected to be considered week to week, per sources. That likely means his Week 2 status is in doubt. The Rams are at Arizona in Week 2 in a later afternoon game, so owners will need a backup plan. Kupp took advantage with 14 catches and 110 yards and could do so again in Week 2 if Nacua is out of action. The Rams could look to Johnson (5-79-0), Robinson and Parkinson at TE to make up for the loss of Nacua, much like they did in Week 1. Whittington, who is a rookie, is another name to watch.

Sean McVay says Puka Nacua is practicing fully.

“He’ll be ready to roll.”

There's been a lot of hand-wringing about Nacua's knee injury, and it has dropped him well out of the first round on many occasions. He remains a a fringe WR1 option if he heads into Week 1 fully healthy.

Tutu Atwell is in the concussion protocol, per Rams spokesperson.

Atwell left the game in the second quarter and it opened the door for Robinson to see more playing time. He finished with a 3-46-1 line on 10 targets. The trend has been for players to miss a game when placed in protocol so this could be a situation to watch heading into Week 15 for Atwell. It would be tough to trust Robinson in typical leagues, especially running behind Kupp and Nacua.

Rookie WR Puka Nacua (oblique) will be listed as questionable for Sunday’s game against the 49ers, but Sean McVay said the Rams are expecting him to be ready to go.

Nacua was a DNP for the last two days, so this is fantastic news. His Week 1 performance was surprising and maybe not sustainable (40.5% target share), but he should absolutely be in fantasy consideration if he's ready by Sunday.

It is clear the Rams are not allowed to have nice things in the Year 2023. Nacua had an incredible debut, accounting for 40.5% of the team's targets in Week 1. Atwell notched 8 targets for 119 yards and would presumably get similar usage if Nacua were to miss this game. It's a shot in the dark, but Demarcus Robinson could get some extra run along the perimeter like he had with the Ravens in '22, as well.

Rams head coach Sean McVay says Cooper Kupp has had a "setback." He calls it a "muscle strain."Day-to-day, per McVay.

"We're obviously a much better team when he's out there."

These minor setbacks seem to be adding up for the 30-year-old Kupp's hamstring. Though fantasy drafters should refrain from overreacting, this certainly isn't a good look. Moving the surrounding cast of Ja'Marr Chase, Tyreek Hill, and Stefon Diggs over Kupp is not out of the question as it stands.

Per Rodrigue, it’s a little more complicated than names on a list. Limited to just the No. 3 position written on paper, it might be between third-year receiver Tutu Atwell and rookie Puka Nacua. Nacua had a significant workload in spring OTAs despite his rookie status, and that has not changed. Over the next few weeks without Kupp, he’ll vault into an even larger role alongside the more veteran players.

Rodrigue also mentioned that even if Cooper Kupp were to miss extended time, it's unlikely that any one player would somehow take over his entire workload, which falls in line with what we saw in 2022. Veteran Atwell's path to the WR3 slot is dependent on him being able to "do it all," which is a tall task for a player of his stature.

As it stands, both Atwell and Nacua make for very interesting dart throws in best ball drafts, particularly when you already have Matthew Stafford rostered.
