3 key matchups: Rams at Falcons

Here are the three key matchups when the Rams (3-3) face the Falcons (1-5) at 1 p.m. Sunday at Mercedes-Benz Stadium.

Rams DT Aaron Donald vs. Falcons RG Jamon Brown: The disruptive Donald is off to another fine start. He has 20 tackles, three sacks and leads the NFL with eight tackles for losses. Last season, he led the league with 25 tackles for losses. Brown will get some help from center Alex Mack.

Rams WR Cooper Kupp vs. Falcons DB Isaiah Oliver: Kupp leads the Rams with 45 catches for 522 yards and four touchdowns. Oliver, who was benched in the Houston game, likely will have to play, with Desmond Trufant trying to come back from a toe injury.

Rams FS Eric Weddle vs. Falcons QB Matt Ryan: Weddle is in his 13th season in the NFL. "He really knows the game from the 22-man perspective," Rams coach Sean McVay said. "He's still got great movement. He's tough. He's got great ball skills. He's been really big bright spot for our defense this year." Ryan, who didn't have an interception against the Cardinals in his most recent outing, will match wits the cagey Weddle, a six-time Pro Bowler.
