NFL notebook: Niners nose tackle Dorsey suffers torn left biceps
San Francisco 49ers nose tackle Glenn Dorsey has a torn left biceps muscle and will undergo surgery, a person with knowledge of the injury told the Associated Press on Saturday.
Dorsey left Friday's practice with the injury. It is likely he will miss the entire 2014 season.
The Niners had a day off from training camp Saturday.
Losing Dorsey would be a huge blow 11 months after 2013 starting nose tackle Ian Williams went down with a season-ending ankle injury in a Week 2 loss at Seattle.
Williams has undergone multiple surgeries and is currently on the physically unable to perform list. Mike Purcell, an undrafted free agent last year, could be an immediate option to fill the void left by Dorsey as San Francisco gears up for its preseason opener Thursday at Baltimore.
In March 2013, Dorsey signed a two-year contract that could pay him up to $7 million with incentives.
Brees sits scrimmage
Saints coach Sean Payton says Drew Brees was held out of an intrasquad scrimmage to rest a sore muscle on the left side of his abdomen.
The absence of New Orleans' star quarterback didn't stop rookie receiver Brandin Cooks from setting himself apart in the first scrimmage of training camp.
Cooks racked up more than 100 yards receiving on just a handful of receptions, highlighted by a twisting, falling catch of a deep pass from second-year reserve quarterback Ryan Griffin.
Clowney leaves early
Texans rookie Jadeveon Clowney was carted off the field during practice, but coach Bill O'Brien said it wasn't serious, according to multiple reports.
The No. 1 overall pick, Clowney iced his right leg before leaving early for the day.
“We're just trying to manage him,” O'Brien told the Houston Chronicle. “He's coming off of surgery and we're just trying to manage him. He's out there and he wants to go every rep. And I'm sure just like all the guys, after seven practices I'm sure he's a little sore and we'll just continue to manage him.”
