DETROIT — Before he exited Thursday’s game against the Detroit Lions with a concussion, Dallas Cowboys receiver CeeDee Lamb had a field day at the expense of D.J. Reed — something the veteran defender openly acknowledged.

According to the NFL’s Next Gen Stats, Reed covered Lamb on 13 snaps during Detroit’s 44–30 win at Ford Field. Over that span, Cowboys quarterback Dak Prescott completed all five of his targets to Lamb with Reed in coverage for 105 yards. Lamb finished with 121 receiving yards overall.

Reed, appearing in just his third game back after missing a stretch of the season with a hamstring injury, said that while he’s healthy, he still needs more practice reps and game action to feel fully confident. But he gave Lamb full credit.

“I didn’t play good. CeeDee won the matchup,” Reed said. “But (Cowboys receiver George) Pickens—I thought we held him. For what he has been doing, I thought we held him pretty good. Rock (Ya-Sin) and Amik Robertson did a great job on him. And yeah—overall, we got the dub. Got a few takeaways, so that’s always important—turnover ratio. And our offense played well. I thought we played good on special teams for the most part, and we played complementary football.”

While Lamb and Ryan Flournoy — who finished with nine receptions for 115 yards and one touchdown — both had strong outings against Detroit’s secondary, Pickens was largely contained. He recorded five catches for 37 yards, with his biggest play an 11-yard gain that resulted in a collision with Lions safety Thomas Harper, who left the game to enter concussion protocol.

Week 15 will not get any easier for Reed or the Lions’ banged-up secondary. With Kerby Joseph’s knee status unclear and Brian Branch now joining cornerback Terrion Arnold on season-ending injured reserve after tearing his Achilles on Thursday, Detroit’s depth is thinning quickly.

The Lions now hit the road to face a red-hot Los Angeles Rams team led by quarterback — and former Lion — Matthew Stafford, who has a dynamic receiving duo in Puka Nacua and Davante Adams.

When asked how quickly he can move past his performance against Dallas and shift into Rams preparation, Reed didn’t hesitate.

“Twenty-four-hour rule,” Reed said. “Watch the film tonight on the tablet, chill with the film after tomorrow. Shoot, I’m going to start watching L.A., but we’re going to meet probably two or three days from now. We got a 10-day period and go over the game, but I’m going to watch it today.”

One thing Reed can hang his hat on: he finished Thursday with the game-sealing interception, eliminating any chance of a Cowboys comeback with 1:18 remaining. When Flournoy caught a short pass, Lions safety Daniel Thomas and Reed arrived simultaneously, with Reed ripping the ball away to secure the pick.

“I was tired as hell, bro,” Reed said when describing what he saw. “I was talking to myself like, ‘Bro, if he runs this dig, I’m going to go get the (ball).’ He actually had it, and I took it from him. I was like, ‘Bro, I need that.’

“I had like 10 targets. I’m like, shoot, I got to get a pick. I got to do something right. I was out there swimming. They had me today—I ain’t going to lie. But that’s the life of a corner. You know what I’m saying? You guard the (No. 1 option), want to be consistent, but sometimes stuff happens. They get paid too, so credit to them.”
