The Rams didn't quite come out clean in terms of injuries in Thursday night's 41-39 victory over the 49ers.

Wide receivers Sammy Watkins and Tavon Austin have both been placed in the concussion protocol.

"We'll continue to monitor them," head coach Sean McVay said. "And, hopefully, we'll get some good news on them in the upcoming days."

Watkins had his best game as a Ram so far on Thursday, making six receptions for 106 yards with two touchdowns. Perhaps his most impressive play was reeling in a 47-yard pass on the left sideline from Goff early in the third quarter.

"Unbelievable," McVay called it. "Those are the types of plays that make Sammy a special player. That's why he is who he is. I think it was exciting to see a handful of plays he made."

Watkins was shown on the television broadcast heading to the locker room with medical staff midway through the fourth quarter.

McVay said safety Lamarcus Joyner suffered a hamstring strain and will be day-to-day heading into next week. Joyner was injured in the second quarter and did not return.

And center John Sullivan will also be day-to-day with a groin injury he suffered early in the third quarter. Both McVay and quarterback Jared Goff praised backup center Austin Blythe for the way he was able to keep the offense operating smoothly in the second half. McVay said Blythe was presented a game ball for his performance.

"Austin was able to come in and make it fairly seamless and do a great job," Goff said. "Without what he did there who knows? He stepped up and had a great day."

"Austin Blythe did excellent, he did a great job," McVay said. "In terms of taking command, controlling some of the calls that are required up front — because we do put a lot on our center — very pleased with Austin."

If there's a silver lining, the Rams now have 10 days between Thursday's game and their Week 4 matchup against the Cowboys. With a couple days off before getting back to practice on Monday, McVay said he did address the team about making good choices. Though he didn't seem too concerned about any potential issues.

"You say, 'Hey, continue to protect the team. Always be mindful of that. Be smart, enjoy yourselves, let yourself get away and get your mind refreshed and recuperated for when we come back on Monday. But be smart,'" McVay said. "The thing that you do feel good about is that up to this point, everything that we've seen is we've got the right leaders in place where kind of they understand what's to be expected. They're setting the standards themselves, and I think that's when you have that chance to see it sustain over time."
