Browns coach Mike Pettine's first day as a 49-year-old was a typical Friday around the Cleveland Browns practice facility.

Here's what we gathered from the locker room after the final practice before Sunday's showdown with the Raiders.

1) Xavier Cooper poised to play if Desmond Bryant can't

Browns starting defensive lineman Desmond Bryant didn't practice for a third consecutive day Friday and is considered questionable Sunday against the Raiders. If the veteran can't play because of his lingering shoulder injury, rookie Xavier Cooper could go from the sidelines into a major role against the Raiders.

Cooper, Cleveland's third-round pick in the 2015 NFL Draft, had a productive preseason that included three sacks, but was inactive for the first two games. Coach Mike Pettine recently said it was merely a product of the Browns defensive line's depth and health and reiterated that point after Friday's practice.

"If he has to go, we're looking forward to seeing him," Pettine said. "Similar to Nate (Orchard), sometimes when people see guys inactive they think it's a negative thing and the only negative is depth at position where you have to have seven guys inactive, and he's been a victim of the number these first two weeks. We're very pleased with where Coop is and if he does have to go we're looking forward to seeing him play."

Pettine said Cooper picked up Bryant's repetitions at practice throughout the week and worked as both a member of the regular defense and scout team defense.

"If he has to go he'll be ready," Pettine said.

2) High praise for Raiders WRs

Joe Haden didn't shy away from his respect and praise for Oakland's wide receiver tandem of Amari Cooper and Michael Crabtree, who have combined for 26 receptions, 204 yards and two touchdowns in the first two games.

Neither Cooper, a star rookie out of Alabama, or Crabtree, a free-agent acquisition, were on the field last year when Cleveland beat the Raiders and then-rookie quarterback Derek Carr.

Haden likely will spend time guarding both Sunday at FirstEnergy Stadium.

"Cooper, I have been watching him on film. That dude is going to be special," Haden said of the third overall pick in the 2015 NFL Draft. "He has a really good stop-and-start, his burst, his body control, runs really good routes. He is growing and growing from the first time I have seen him play. He has a lot of potential to be really good in this league.

"Crabtree is a veteran. He is crafty, runs good routes and catches the ball. I think their receiving corps has definitely upgraded from when we played them (last year). Those dudes just know how to make plays with the ball in their hands. They are stepping up."

3) Busy Sunday for the McCowns

For the first time since Josh McCown was with the Raiders, he'll share the national stage with his brother on an NFL Sunday.

McCown's younger brother, Luke, was named the starting quarterback Friday for New Orleans, which will face Carolina without Pro Bowl quarterback Drew Brees under center.

It will mark the first time Luke McCown, a former Browns quarterback, starts a game since 2011 and the first time the brothers start on the same day since 2007.

"I'm excited for the opportunity Luke has to play," McCown said. "My parents are actually in Charlotte this weekend for the game but will have fun following our game closely as well."

4) Pettine's 2-point stance

The Browns have yet to attempt a two-point conversion since the NFL moved back the extra point, but that doesn't mean Pettine isn't open to it.

"We do a decent amount with it, but still feel that the conversion rate is high enough that I think we'll be a situational go-for-two team," Pettine said. "If it ever presents itself during the game where it's either a penalty where it puts it inside the 2 (yard line) or the situation calls for it, we'll be there as well."

NFL teams have already converted seven two-point conversions this season. The extra-point success rate is still high but has dropped a bit.

"I think when we get into some less than ideal weather games … you're not thinking that it's 90 something percent," Pettine said, referencing the league's success rate on extra points. "That potentially could change our thinking."

5) Just doing his job

Pierre Desir delivered one of the final blocks on Travis Benjamin's 78-yard punt return for a touchdown last week against the Titans.

It just happened to be on Tennessee punter Brett Kern, whose faceplant to the turf promptly went viral on social media. Benjamin hurdled Kern on his way to the end zone.

"I wasn't picking on him," Desir said. "I was just trying to block him. That is all."
