The Browns became the sixth pair of twins selected in the same draft in the last 40 years. Sydney was selected in the third round by the Eagles (No. 66 overall) and Chase, a running back, was selected in the fifth round by the Bengals (No. 163 overall).

And even though they're now back on different teams, the twins still talk on the phone and talk every day – but not this week.

“When will it end? Probably tonight,” Sydney said in the locker room at MetLife Stadium on Sunday. “I'll call him because they just finished their game too, and we'll pop in for a bit and then probably chat about what we're going to do and stuff, and I'll see him at the end of the week and after the game, so just a week.

“It's going to be hard, but this is my husband, someone I talk to every day, who's almost like my therapist in a lot of ways, so it's going to be hard. I haven't even thought about it, but I said earlier this week it will be like a week-long separation for both of us.

It was questionable whether Sydney would return in time for Sunday's game against the Bengals after recovering from a torn ACL. Brown worked diligently on the comeback process and was able to return a week before the match at the spot where he sustained the injury last year.

“I tore my ACL last year for a reason and it was precisely because of this opportunity that I had to develop a strong mindset and go through this process with Jerome (Reid, senior athletic trainer) and I am Jerome Reid and Tom (Hunkele) very grateful “I have a lot to thank them for,” Brown said.

People around the NovaCare complex noticed the work he put in to come back. Before Brown was cleared to practice, he stood in the end zone and watched every play during training camp and imagined himself out there.

“Everyone saw how hard he worked to get back. This guy just attacked his offseason trying to get ready to play football again and the way he attacked it, in rehab, in the training room, but also just mentally. “Reps” said head coach Nick Sirianni. “Every time you watched him, he was getting mental reps, always behind the game. He always just took steps to simulate that he was in there and that this guy was preparing for this moment, so I'm glad he's back and I think it would be sweet if he was this week could pull off a cool punch against his brother.

While this will be a historic and unforgettable memory for the Brown twins, both know that in the end, what's most important to them is going out and getting a win for their team.

“I have my brother on the other side of the ball, but at the end of the day it's just the Cincinnati Bengals against the Philadelphia Eagles, so I'm not going to make it anymore and just play for what I want,” said Sydney.

Although it's the first time in their lives that the brothers have been on opposite sides, it won't be the first time this season that an Eagles safety has faced off against his twin.

Tristin McCollum and his twin Zyon, a cornerback, were on opposite sides when the Eagles played the Buccaneers in Week 4.

As Sunday approaches, Sirianni knows what the matchup means for the Brown brothers.

“I preach a lot about family. I think there is a bond between twins that I will never understand. I'll walk past Sydney and he'll be talking to his brother, so I think that's a pretty cool thing they're doing.” “I'll be playing against each other this week,” Sirianni said. “And I think of the world of both. I think of the world of Sydney because I'm around him every day, but I think his brother is a damn good football player. I'm looking forward to this clash and this duel if it happens.”
