LeSean McCoy continued his slow start to the 2014 season, rushing 17 times for just 10 yards in the Philadelphia Eagles' 26-21 loss in Week 4 to the San Francisco 49ers.

“It sucks,” McCoy said. “I thought we were going to win this game. There are so many plays that we could have made, but we didn’t. I thought we were going to pull it off like usual, especially getting down there at the 2-yard line.” 

“We are not getting it done,” McCoy said. “Not executing. We will watch this tape and learn from this and move on.” 

McCoy said he was “embarrassed” and said he didn’t want to discuss the running game.

Asked if he was healthy, McCoy gave a curious answer. 

“I doesn’t matter,” he said. “It doesn’t matter if I’m healthy or not. We have to win games. I am fine.” 

Vernon Davis missed Week 3 with a deltoid ligament injury in his left ankle and will be a game-time decision for Week 4 against the Philadelphia Eagles.

Davis was initially told he would miss 2.5 weeks with the injury.

"It feels a lot better than last week," he said.

Davis has practiced in a limited fashion all week and was listed Friday as questionable.

Arian Foster will be a game-time decision and is questionable for Week 4 due to a hamstring injury.

Foster was a late scratch in Week 3 due to the injury.

Foster rushed 55 times for 241 yards in the first two weeks of the season. 

Calvin Johnson returned to practice for the Detroit Lions on Friday after missing two days with an ankle injury.

Johnson did a full complement of work during the team's individual workouts.

Johnson plans on playing against the New York Jets in Week 4.

"He's one of those guys that physically, he's an unusual individual," Lions coach Jim Caldwell said before practice Friday. "He responds quickly to treatment. He bounces back pretty quickly for the most part. What would ordinarily take some guys a little bit longer, he seems to be able to fight his way through it.

"He has an extremely high pain tolerance, as well, and he prepares and takes care of his body every single day of the year. That's where his focus is, and I think he benefits from that sort of regimen."

The Minnesota Vikings want to make sure they get more touches for Cordarrelle Patterson than they have over the first three weeks.

“We need to continue to find balance,” Norv Turner said, via the Minneapolis Star Tribune. “When everyone talks about balance, they think it’s run and pass. It’s balance in terms of getting all of our players involved. In my experience when they’re going good, they take someone away or concentrate on someone to give someone else the opportunity. Cordarrelle is a different situation he was a year ago. He’s growing and teams are matching with him and they’re concentrating on him. We’ve got to continue to work ways to get him the ball.”

Demaryius Thomas has started slow during his first three games of the 2014 season.

"I know I can be better, I know I can play better, I know I can do things better than I've done them so far,'' Thomas said just before the Broncos adjourned for their bye weekend. "I haven't done the things I know I can do.''

Thomas has just 48, 62 and 31 yards in the first three games.

He has one touchdown catch, and what he called "the thing I have to fix'' is the most glaring number of all: his dropped-pass total. Thomas has already dropped four passes this season.

Thomas dropped just five balls in all of 2013.

"I just haven't been consistent, and it bothers me,'' Thomas said. "I think about it, I keep practicing hard, doing the things I need to do. I want to make it right.''

LeSean McCoy has just 175 yards on 60 rushes this season after finishing 2013 with 1,607 yards and citing a goal of 2,000 before the season started.

"I don't think I'm struggling at all," McCoy told CSNPhilly.com. "I don't know what you mean by that. I don't think I'm struggling, at all. So I don't know what you mean by that." 

"I think it's different how they're playing us this year," Chip Kelly told reporters. "We've seen different looks in terms of the three games we've played this year compared to last year. I think LeSean's doing everything possible. Again, if that's how you're going to do it, and we're going to end up with 30-whatever points a game and continue to be productive on the offensive side of the ball, it's ultimately that. But also you're down four linemen that you had that were running in front of him last year, too. So I think sometimes when we're running the play, there is a lot better push at the point of attack, and that doesn't have anything to do with the running back from that standpoint. It's kind of what it is right now."

Le'Veon Bell leads all NFL players with 461 yards from scrimmage through the first three weeks of the season.

"Let me just say this: Right now, I would take Le'Veon Bell over any running back in the league," NFL Media's LaDainian Tomlinson said on Tuesday's edition of NFL Total Access. "... He can do it all, people. He can run inside, he has the speed to turn the corner, he can catch the football, he's versatile, he's athletic. I love Le'Veon Bell."

Adrian Peterson is on the exempt list as he faces child abuse charges, while LeSean McCoy and Jamaal Charles have yet to regain their 2013 form.

Dennis Pitta underwent surgery on his dislocated right hip and is lost for the year. The procedure comes one day after the tight end suffered the non-contact injury in a Week 3 win over the Cleveland Browns.

It's the same right hip that Pitta fractured and dislocated last summer, an injury that cost him much of 2013.

The nature of the injury brings into question whether Pitta's playing career is now in jeopardy.

"I don't know the ramifications of that long term," Harbaugh said. "I'm going to be really hopeful for Dennis' return and I'm sure we'll learn about that in the coming weeks."

Kyle Rudolph is expected to miss six weeks with sports hernia surgery.

Rudolph left the Minnesota Vikings' Week 3 loss to the New Orleans Saints with a groin injury.

The Vikings have targeted Rudolph 17 times this season.
