John Harbaugh "concerned" by defense

Baltimore Ravens head John Harbaugh has admitted that he is "concerned" about the way his side are finishing games on defense.

The Ravens conceded two late touchdowns in their win over the Minnesota Vikings that required a late score of their own to turn the match back in their favour.

He told the Baltimore Sun: "I'm concerned about it. Finishing on defense has been our biggest issue. That's something we have to be better at.

"I think we're a very good, sound defense assignment and technique-wise throughout the course of the game and the course of the season.

"In those situations, we haven't been as good as we have the rest of the time. That's something we've got to clean up. To me, that's not a hard fix."

The Ravens face the Detroit Lions in their week 15 clash on Monday.
