SANTA CLARA, Calif. -- LeSean McCoy didn't want to talk about it after the game.

The Eagles fell to the San Francisco 49ers 26-21 on Sunday at Levi's Stadium after McCoy gained just 17 yards on the ground on 10 carries. He averaged 1.7 yards per carry and his longest gain went for just five yards. In total, the league's top-ranked rushing team in 2013 gained 22 rushing yards.

"We're just not getting it done," McCoy said. "We're not executing."

Despite the struggles, McCoy nearly scored what could have been the game-winning touchdown. On second-and-goal from the 6-yard-line, McCoy ran a sweep to the left side of the field where the Eagles had three receivers to block. McCoy got to the 1-yard-line.

However, the Eagles could not put the ball in the end zone after two incomplete passes by quarterback Nick Foles. McCoy was "shocked" that the Eagles didn't score. He was just as surprised that the Eagles' offense was unable to cross midfield until the next-to-last drive of the game.

"There were so many plays that we could have made," McCoy said.

Left tackle Jason Peters was also at a loss for why the run game has struggled.

"I'm not sure. I've got to go back and look at the film tomorrow and see what went wrong," Peters said. "All you can do is your job on a certain play, when you look back and it's not a good play, you really don't know what went wrong."

Peters is quick to point out that the Eagles were unable to run the ball last week against Washington and still came out with the win. The Eagles nearly stole a win on the road Sunday.

"We won last game and the running game was not up to par like it's supposed to be," Peters said. "Guys are going to come in trying to stop (McCoy). We've got to find other ways to win."
