"It's one of those things that, like Coach Harbaugh always tells us, he's tougher than a $2 steak," 49ers linebacker Patrick Willis said. "We know he's going to be alright. We know we have a bunch of great coaches here that keep everything on track, and we're going to practice today as if he was here."
Team spokesman Bob Lange said no incident had occurred at the facility. Instead, Harbaugh had visited with doctors Wednesday night after feeling ill, and they advised him to have the procedure done at Stanford Hospital.
Players were informed of Harbaugh's hospitalization by assistant head coach and special teams coordinator Brad Seely during Thursday morning's walkthrough. Seely also oversaw team meetings and the afternoon practice.
Jets owner: 'I didn't sign up for 3-6 season'
Woody Johnson expects the New York Jets to turn things around and fast.
A 3-6 start has the owner just as disappointed as the fans, who were expecting a lot more this season from coach Rex Ryan's team.
"The record says what's going on," Johnson said during practice Thursday. "We're a 3-6 team. Are we happy? Are they happy? Are the players happy? I know the fans aren't happy. The answer is no. We're not happy. We're not happy with 3-6.
"I didn't sign up for a 3-6 season. We haven't had one of these in a while. I'm not happy about it, yet I am optimistic that some of these things can be corrected."
Johnson would not comment on the immediate futures of Ryan or general manager Mike Tannenbaum, saying it's his policy not to address those things during the season. But he made it clear that things need to get better for his team, which is heading to St. Louis on a three-game losing streak.
The Jets are coming off a lackluster 28-7 loss at Seattle last Sunday that left Johnson frustrated.
"In a lot of pain this week, again," Johnson said. "To lose in this game, it's a miserable experience and it's tough tough to lose any game, particularly as many games as we've lost this year."
There has been some speculation by fans and media that Johnson was solely behind the Tim Tebow deal in March, hoping to boost sales of tickets and personal seat licenses. Johnson turned a bit testy when asked about that.
"This, I really want to clear up," Johnson said. "You guys have been accusing me, this phony story of me being more concerned with PSLs or cash or something else. My job 1, 2 and 3 is to win games. That's why I got into this to begin with. It's to win games. It's not to sell PSLs or to sell hot dogs."
Around the league
Cowboys • Receiver Dez Bryant reached an agreement with prosecutors that could lead to dismissal of a family violence charge over a dispute with his mother. Bryant is attending anger management sessions, and the Dallas County district attorney's office will dismiss the misdemeanor charge if the third-year receiver stays out of trouble for a year. Bryant was arrested in July in suburban Dallas after he allegedly hit his mother, Angela Bryant, in the face with a ball cap.
Broncos •Elvis Dumervil plans to test his sprained left shoulder at practice Friday in hopes he can play Sunday against San Diego. The two-time Pro Bowl defensive end was injured at Carolina last weekend but medical tests this week showed no torn muscles or ligaments.
Browns • Starting cornerback Joe Haden was not at Thursday's practice because of an oblique injury. He was limited on Wednesday with the injury but said afterward he expected to play this week at Dallas.
Texans • Former punter Brett Hartmann has sued the county agency that operates Reliant Stadium, blaming "unsafe turf" for a possibly career-ending knee injury. He tore his left anterior cruciate ligament and fractured a bone in Houston's 17-10 win over Atlanta last Dec. 4 when he caught his left foot in a seam between turf palettes.
