Falcons defense suffers another blow

Safety Ricardo Allen of the Falcons won’t play again this season because of an Achilles injury.

Atlanta starting safety Ricardo Allen will miss the remainder of the year with a torn left Achilles tendon, dealing another blow to the Falcons’ ravaged defense.

Allen, who had 17 tackles and an interception, is the third defensive starter to go on injured reserve. Atlanta also lost strong safety Keanu Neal and middle linebacker Deion Jones, both Pro Bowl alternates.

Coach Dan Quinn said the Falcons will look to add another safety but rebuffed the suggestion that the team might acquire Seattle’s Earl Thomas or sign free agent Eric Reid, another former Pro Bowler.

Concern for Griffen

Minnesota general manager Rick Spielman said the team is “concerned” for defensive end Everson Griffen, who missed Sunday’s game with what the team listed as a knee injury and Monday’s practice.

However, coach Mike Zimmer said the three-time Pro Bowler from USC was dealing with a “personal matter,” and KSTP-TV reported, citing unnamed sources, that Griffen was involved in a weekend disturbance at a downtown hotel.

According to Minneapolis police spokesman John Elder, officers were called to the hotel Saturday afternoon after a man threatened physical violence.

The man was departing upon their arrival, and after questioning he was released at the scene. Elder did not confirm that Griffen was the man.

No on Kaepernick

San Francisco coach Kyle Shanahan, reeling from the loss of Jimmy Garoppolo — “It was hard waking up today,” he said — said veterans Tom Savage, Kellen Clemens, possibly T.J. Yates and Matt Moore will be brought in for tryouts this week, but not Colin Kaepernick.

“That’s what I said last year and it’s the same situation now,” Shanahan said.
