Chiefs’ Mahomes shreds 49ers; Garoppolo injured

More importantly, all those touchdown tosses have the Chiefs 3-0. They are the third team to score at least 38 points in each of the first three games, joining 2007 New England and the 1967 Baltimore Colts.

“We’ve got a bunch of weapons,” said Chiefs running back Kareem Hunt, who added his first two touchdown runs this season, “and Pat is just a competitor. I knew that from the day we met, when we got drafted together. We said one day we were going to take over the Chiefs Kingdom.”

The Chiefs have clearly found their long-term answer at quarterback.

The 49ers? They have a whole lot of questions now.

Jimmy Garoppolo left late in the fourth quarter after his left knee buckled during a scramble to the sideline. He was crushed on his throwing shoulder by the Chiefs’ Steven Nelson, but the damage was already done, and the 49ers’ franchise quarterback was carted off to the locker room.

“We fear an ACL,” 49ers coach Kyle Shanahan said. “We’ll find out for sure tomorrow.”

The 49ers (1-2) trailed 35-7 late in the first half before rallying behind Garoppolo, who threw for 251 yards and two touchdowns. Matt Breida added 90 yards rushing and Alfred Morris scored on the ground as San Francisco clawed to within 35-24 late in the third quarter.

It was still 38-24 when the 49ers produced a grinding, 17-play drive that wiped out more than half the fourth quarter. But it ended in a strange sequence that began with Garoppolo taking the shot from Nelson along the sideline, rather than stepping out of bounds and avoiding the hit.
