Cleveland Browns coach Mike Pettine gave no credence Wednesday to stories on the NFL Network that the team is trying to trade quarterback Brian Hoyer to the Houston Texans.

"'Stories' is a good word to apply to that," Pettine said.

Pettine was asked whether there is absolutely nothing to that NFL Network report.

"We're not going to comment on every story that's out there," he said. "We made a move to strengthen our quarterback room, and you just get these stories coming out. I don't want to be in the habit of commenting on all of them. I really addressed that situation yesterday."

On Tuesday, Pettine announced that rookie Johnny Manziel and the veteran Hoyer will split first-team reps in Monday night's preseason game against the Washington Redskins. The Browns also signed quarterback Rex Grossman, who was with Washington from 2010 to 2013 where Browns offensive coordinator Kyle Shanahan was the offensive coordinator for the Redskins.

Pettine said Grossman, a 12th-year veteran, could help both Manziel and Hoyer. Pettine said Grossman stepped right in with his knowledge of the offense.

"He went in the meeting room and they have all the installations up on the board and I think he processed it pretty quickly," Pettine said of Grossman. "There were a couple of minor tweaks to it, but it's all stuff that he's run before that he's comfortable with."

Pettine, speaking on ESPN Radio's "Mike & Mike" show Wednesday morning, acknowledged that Manziel is "slightly ahead" of where the Browns expected him to be.

"He's been impressive. He's probably slightly ahead of the learning curve where we figured he would've been," Pettine said. "I think a big part of it for him is it's essentially him getting the playbook and it has been for a while. And I think he's finally starting to settle down with it.

"It's just a lot of information to process. And he's done a good job of it. We're very pleased with where he is."

Pettine is confident the quarterbacks can handle the no-huddle offense which the Browns used in practice and want to incorporate offensively at some point.

"Today was the first set of doing it," Pettine said after Wednesday's practice. "We were pretty basic offensively with the volume that we had no-huddle, but I think it's to any quarterback's advantage to be able to get up on the ball quick and force a defense to not be able to substitute and maybe be a little bit more vanilla with their calls or more worried about getting lined up then getting in advance detail.

"You see some teams that play well when they have that time to reset in between, and then I think you just need that in your arsenal to kind of unnerve a team, the ability to go no-huddle."

Meanwhile, CBS reportedly plans to send its No. 1 announcing team of Jim Nantz and Phil Simms to call the Browns opener at Pittsburgh on Sunday, Sept. 7 in anticipation of Manziel's debut.
