CSN Philly believes "it looks like a stretch," for tight end Clay Harbor to return for his fourth season with the Eagles.

Harbor is buried on the depth chart behind Brent Celek, James Casey and rookie Zach Ertz, making him likely to be cut if the Eagles can't trade him. The tight end has been mentioned as a possible target of the Patriots to replace Aaron Hernandez, but we believe they can fetch a more talented player than Harbor via trade.

The Philadelphia Daily News suggests TE Clay Harbor as a possible target for the Patriots.

A chronic underachiever since the Eagles drafted him in 2010, Harbor could likely be had for a sixth- or seventh-round pick. He's behind Brent Celek, James Casey and rookie Zach Ertz on the Eagles' depth chart. Harbor is versatile and athletic enough to play a little flex tight end for the Pats, but he's far from their answer as they scramble to replace Aaron Hernandez. Chiefs TE Tony Moeaki, another possible trade target for New England, has more natural talent.

Eagles TE Clay Harbor is not switching positions despite spending one day at outside linebacker in OTAs.

"I'm a tight end, and for emergency situations, and just versatility purposes, for me, I'm learning (outside linebacker)," Harbor said Saturday. "Something happens to where you need an outside linebacker, it would be good to know some. Coaches talked to me, 'Would you mind learning a little bit of linebacker, just in case?'" Harbor did go on to admit the Eagles have a "lot" of tight ends, and that "there's a good chance that I might not be here." A three-year veteran going on 26, Harbor's NFL future should remain at tight end.

The Eagles are "temporarily" moving TE Clay Harbor to outside linebacker.

It doesn't sound like a permanent move, but the Eagles obviously don't think highly enough of Harbor to let him work on learning the new offense. The 2010 fourth-round pick has been an underachiever since entering the league, and he's entering the final year of his rookie contract. Harbor is clearly the odd man out at tight end after the additions of Zach Ertz and James Casey.

Philly Mag believes TE Clay Harbor is squarely on the roster bubble.

Harbor, an underachiever since being selected in the fourth round of the 2010 draft, is entering the final year of his rookie contract. The Eagles signed James Casey and also have Brent Celek on the roster. Harbor will likely compete with a mid- to late-round pick.

Eagles TE Clay Harbor said he broke three small bones in his lower back during last Thursday's loss to the Bengals.

Harbor sustained the injury in the first quarter and still finished out the game. He's since been placed on injured reserve. Brent Celek is back from his concussion and will start Sunday's game against the Redskins.

Eagles placed TE Clay Harbor (back) on injured reserve, ending his season.

Harbor played through a deep contusion to his lower back after getting drilled just before halftime last week. Brent Celek (concussion) returns to the lineup this week with Emil Igwenagu as the backup. Harbor enters the final year of his rookie contract in 2013.

Eagles TE Clay Harbor suffered back spasms in Thursday's loss to the Bengals.

Harbor was drilled in the back just before halftime. "I really couldn't move the way I wanted to or do anything the way I wanted to after that play," explained Harbor. "I was just laboring and trying to fight for my teammates at that point knowing Brent's out and obviously I have to go." Brent Celek is expected to return for Week 16 versus the Redskins.

Clay Harbor, who started in place of Brent Celek (concussion), caught three passes for 30 yards in Week 15 versus the Bengals.

Clay Harbor is starting in place of Brent Celek (concussion) versus the Bengals in Week 15.

It's the first game Celek has missed since entering the league in 2007. Harbor finished with a 6/52/1 stat line in relief of Celek last week, reeling in all six targets. Rotoworld ranks him 20th among fantasy tight ends for Week 15.

Clay Harbor caught six passes for 52 yards with a touchdown in the Eagles' Week 14 win over the Bucs.

Brent Celek left with a concussion sustained on the very first drive of the game. Harbor, a natural pass-catcher, responded by hauling in all six of his targets, including a tough catch in the back of the end zone with just under four minutes to go. Celek is highly unlikely to be cleared in time for Thursday's game against the Bengals, leaving Harbor as a desperation TE2.

Clay Harbor remains the favorite to back up Brent Celek this season.

The Eagles brought in veteran Donald Lee, but the blocker hasn't been able to unseat Harbor yet. Harbor, a 2010 fourth-rounder, fits better on the roster thanks to his special teams ability.

Eagles backup TE Clay Harbor recently underwent sports hernia surgery.

Harbor played most of the season with the injury, catching nine passes for 72 yards as a rookie. The normal timetable for a recovery is 4-8 weeks, and Harbor expects to be ready for spring workouts.

Clay Harbor caught four passes for 32 yards in Sunday's loss to the Cowboys.

The Eagles rested Brent Celek, so Harbor piled up a team-high nine targets. The rookie fourth-rounder had a hideous drop deep down the field in the second half, but otherwise handled himself well. With Cornelius Ingram's career in jeopardy due to multiple knee injuries, Harbor is the favorite for No. 2 tight end duties next year.

Clay Harbor has taken over the as Eagles' No. 2 tight end, confirms beat writer Geoff Mosher.

Cornelious Ingram's multiple major knee surgeries have sapped his trademark speed and quickness, so Harbor is in. The fourth-round rookie will be on the field in two-tight end sets, but isn't a great pass-catcher. If Brent Celek were to get hurt, owners should look elsewhere.

Eagles signed fourth-round TE/FB Clay Harbor to a four-year contract.

An intriguing athlete out of small school Missouri State, Harbor was announced as a fullback by the Eagles after playing both positions in college. For now, he's practicing with the tight ends, but his ideal role is H-back. He'll be limited to special teams work as a rookie.

The Eagles have listed fourth-round pick Clay Harbor as a fullback.

The 6'4/243-pound small-school product will be a traditional H-back in Philly's West Coat offense, likely lining up in the backfield on occasion, catching some swing passes, and blocking linebackers. Some teams considered him a tight end. Harbor's primary duties initially figure to be on special teams.

Eagles selected Missouri State TE Clay Harbor with the No. 125 overall pick in the 2010 NFL Draft.

A three-time All-Missouri Valley Conference first-teamer, Harbor capped off a strong career in the low-level college ranks with a 59-catch, 729-yard, four-score senior season and was a Combine standout. An H-back type at 6'4/243, Harbor is a nice fit in a West Coast attack like the Eagles, and has lots of special teams tackles on his resume. His addition doesn't speak particularly well to the Eagles' long-term hopes for Cornelius Ingram.
