Ravens pick apart Moore and the Fins

Joe Flacco threw a touchdown pass before being knocked from the game with a concussion and the Baltimore Ravens frustrated quarterback Matt Moore and the Miami Dolphins Thursday in a 40-0 victory.

Alex Collins ran for a careerhigh 113 yards and Baltimore (4-4) returned two interceptions for touchdowns in the most lopsided shutout in franchise history.

In the midst of one of his best performances of the season, Flacco was struck in the helmet by Miami linebacker Kiko Alonso while sliding at the end of an impromptu run.

Flacco’s helmet flew off his head and the 10-year quarterback appeared dazed as he struggled to his feet.

The play occurred with three minutes left in the second quarter.

Alonso was flagged for unnecessary roughness, providing Baltimore with a first down that ultimately turned into a touchdown.

Flacco was placed in concussion protocol and by halftime was ruled out.

He went 10-for-15 for 101 yards, including a 34-yard touchdown pass to Jeremy Maclin.

After losing four of five to fall under .500 for the first time this season, the Ravens put it all together with a showing that included a 63-yard interception return by C.J. Mosley and a 50-yard pick-six by Jimmy Smith.

The Dolphins (4-3) came in with a three-game winning streak after rallying from 17- and 14-point deficits in the previous two weeks.

There would be no comeback in this one, not against a swarming Baltimore defence that limited Miami to 196 yards.

Moore was making his first start of the season for the injured Jay Cutler.

Four days earlier, Moore engineered a win over the Jets after Cutler left with fractured ribs.

In this one, Moore completed 25 of 44 passes for 176 yards.
