PHILADELPHIA - The Eagles' defense just can't buy an interception these days.

The unit enters Sunday's game against Washington with no interceptions in the last 34 quarters, or 8 games. Opposing quarterbacks have thrown 246 passes during that span.

"I wish we could just get about 20 of them, but it doesn't happen like that," defensive coordinator Todd Bowles said Thursday. "But it's not a curse. You just shake your head sometimes, but you've just got to keep plugging away."

The Eagles have seven interceptions this season, tying Dallas, Kansas City and Pittsburgh for the fewest in the NFL. If they don't get one in the next two games, they will set a franchise record for fewest in one season, breaking the record of eight in 1983.

Interceptions weren't a problem for the Eagles early in the season. Four of their seven came in the opening game. Safety Kurt Coleman and cornerback Dominique Rodgers-Cromartie had two apiece in a 17-16 victory at Cleveland. Linebacker DeMeco Ryans grabbed one the next week in a 24-23 win over Baltimore.

But they haven't had one since cornerback Nnamdi Asomugha picked off Detroit's Matthew Stafford in the second quarter of the Eagles' 26-23 loss to the Lions on Oct. 14.

"We've had our opportunities, but we just haven't taken advantage of them," said Rodgers-Cromartie, who dropped a pass thrown by Cincinnati's Andy Dalton last week. "The main thing is to just try to come down with the ball and not try to do too much."

New tight end ready to play

The Eagles signed tight end Evan Moore to replace injured Clay Harbor.

Harbor was placed on injured reserve earlier this week after breaking three bones in his lower back against the Bengals.

Moore, 27, played in 14 games with Seattle this season before being released Wednesday. The Eagles signed him through 2013 after he passed through waivers Wednesday afternoon.

"I caught a red-eye (flight) last night and haven't had any sleep since," Moore said Thursday. "I'm happy to be here. I don't know much about the team other than we have two games left and I want take advantage of this opportunity and try to help the team as much as possible."

The 6-foot-6, 250-pounder has played in 47 NFL games with Cleveland (2009-11) and Seattle and caught 63 passes for 810 yards and five touchdowns. He had his best season with the Browns in 2011, recording 34 receptions for 324 yards and four TDs. He had just one catch for 6 yards for the Seahawks this season.

Eagles quarterback Trent Edwards was his college teammate at Stanford.

"I'm hoping to be ready to play this weekend," Moore said. "I've been on a team for the last 14 games, so it's not like I'm getting off a couch. I just want to play football and this is a great opportunity for me."

Moore will become the first Eagles player to wear No. 86 since wide receiver Reggie Brown, who played for the Eagles from 2005-09.

Ball security

The Eagles'coaches have spent a lot of time this week working with rookie running back Bryce Brown in an effort to cure his fumble-itis. Brown lost four fumbles in four games while LeSean McCoy was sidelined with a concussion. Coach Andy Reid said Wednesday that McCoy will start Sunday but will share playing time with Brown.

"Me and the rest of the coaches are emphasizing ball security to the point of ridiculousness," offensive coordinator Marty Mornhinweg said of their work with Brown. "That's our mentality, to keep emphasizing and drilling it."

Brown could get most of the playing time against the Redskins while McCoy works to get back into shape. The 2011 Pro Bowler went almost a month without being able to run and do other conditioning because he was still suffering symptoms of the concussion he got against Washington on Nov. 18.

"I'm not sure how it's going to go," McCoy said. "We'll find out this week. Not being able to run and stuff for a couple of weeks is tough."

Bumps and bruises

Fullback Stanley Havili (strained hamstring) was the only player to miss practice Thursday and is not expected to play Sunday. Rookie running back Chris Polk will play fullback.
