Here’s how Brissett looked against the Dolphins.

Prior to the hit by the Dolphins’ Kiko Alonso that crushed him into the turf, Garoppolo was shredding the Miami defense, having completed 18 of 27 passes for 234 yards and 3 touchdowns.

With Brady suspended through Week 4, the emergence of Garoppolo had taken a great deal of pressure off of New England, as he opened the season with an upset win on the road over Arizona and got the team off to a host start this week as well.

The injury, which could potentially keep Garoppolo out for multiple weeks, leaves the Patriots with a thin depth chart at the game’s most important position. Third-stringer Jacoby Brissett took over for Garoppolo. Behind a conservative game plan, Brissett completed 6 of 9 passes for 92 yards. Patriots kicker Stephen Gostkowski missed a late field goal to put the game away, but the Dolphins came up short on their final drive.

Pro Football is Back in Los Angeles ... Sort Of

Professional football returned to Los Angeles, or at least something resembling it did, as the Rams held on to beat the Seattle Seahawks 9-3 in their home opener at the Los Angeles Memorial Coliseum. Beating the Seahawks, an N.F.C. West rival, for the third consecutive time likely felt good, but that was tempered by the fact that the Rams have failed to score a touchdown through two games.

Here’s our report from the Coliseum.

The focus before the game was on the injured ankle of Russell Wilson, but the Seahawks may want to be more concerned about the team’s running game. Traditionally a strength for Seattle, Seattle’s runners combined for just 67 yards on the ground, averaging 2.8 yards an attempt. And Seahawks running back Christine Michael lost a fumble late in the fourth quarter to seal the victory for the Rams.

This is the second consecutive season that the Seahawks have gotten off to a rough start, with the team going 0-2 last year before going 10-4 to close the season.
