Harbor figures to secure a roster spot with the Patriots, assuming his current injury issue doesn't linger, but given that the tight end works behind both Rob Gronkowski and Martellus Bennett, fantasy relevance remains a break or two away.
Cook is likely on the PUP list due to foot surgery he had in June. The tight end said he was fully healthy but was likely over exaggerating, and now that Green Bay's medical staff has checked him out, it's clear he needs some more time to recover. It's not clear how long it'll take him to return, but look for Richard Rodgers to see a bulk of the first-team reps as long as Cook is kept out.
Pitta hasn't played in a game since September of 2014, when he suffered a fractured and dislocated right hip for the second time in two years. Retirement was a real possibility at one point, but Pitta reportedly looked good during the Ravens' offseason program. Now 30 years old and still carrying significant risk of re-injury, Pitta will need to compete for a role on a team that also has Ben Watson, Crockett Gillmore (shoulder/back) and Maxx Williams at tight end.
Walford (knee) was able to run during workouts Sunday but will be eased into training camp, ESPN's Adam Caplan reports.
Walford is still working his way back from a knee laceration suffered during an ATV accident earlier this offseason. The ailment prevented Walford from featuring in spring practices, but it appears he's increasing his workload on the verge of training camp. While the Raiders are still expected to ease their second-year tight end back into action, the team will be relieved by Walford's progress, as a knee injury limited him during the first handful of games last season.
Thanks to the procedure, the tight end -- who agreed to a four-year, $20 million contract with the Steelers in March -- was unable to participate in the team's offseason program as anything but an observer, though the 26-year-old has been working on absorbing Pittsburgh's offensive playbook in the meantime. While it remains to be seen how much Green will able able to do on the field next week when training camp opens, there's nothing to suggest that his Week 1 status is in any danger. In the wake of the retirement of Heath Miller, Green is slated to serve as the Steelers' unquestioned No. 1 tight end, an assignment that should allow Antonio Gates' former understudy (in San Diego) to put up fantasy-worthy numbers in 2016.
Pettigrew has been placed on the physically unable to perform list prior to the start of Detroit's training camp.
Pettigrew has been recovering from an ACL tear he suffered in December of last season. Though he's made steady progress, he isn't ready to practice quite yet and will instead participate in off-field activities. He'll be looking to return as soon as possible in order to compete with Eric Ebron (undisclosed), who will handle first-team reps while Pettigrew is sidelined.
Rodgers' 58 receptions last season were the second-most by a tight end in Packers history, but his at times brutal inability to gain yards after the catch caused frustration. In response, Green Bay signed Jared Cook, an excellent athlete, this offseason, but after having foot surgery in June, the veteran could be somewhat limited as the season approaches. That would allow a reportedly more slender Rodgers to continue to see the bulk of first-team reps at tight end, where his consistency and familiarity with the offense could give him a further advantage on Cook when it comes to playing time.
Cowboys executive VP Stephen Jones said Monday that Escobar (Achilles) could be recovered in time to play in Week 1 against the Giants, David Helman of DallasCowboys.com reports. "I think Gavin will be ready to start the season," Jones said.
Escobar tore his Achilles tendon in December, but he appears to be well ahead of schedule in his rehab. Even if he is in the lineup to begin the regular season, though, he's still stuck behind Jason Witten on the depth chart and would be little more than an occasional red-zone option in a stacked passing game.
Although Texans tight ends combined for just 77 targets and 41 receptions last season, Griffin did lead the way with 32 and 20, respectively, despite losing seven games to injury. The team didn't address the position with any notable free agents or draft picks, but rookie UDFA Stephen Anderson could compete for a role in the slot. Houston hasn't had a fantasy-relevant tight end since Garrett Graham put together a solid stretch during the middle of the 2013 season.
Ellison (knee) anticipates a full recovery by training camp, the Twin Cities-Pioneer Press reports.
Ellison suffered a torn patellar tendon in last year's season finale against the Packers, but hasn't reported any setbacks in his recovery and anticipates being 100 percent for training camp. He enters camp firmly behind Kyle Rudolph and MyCole Pruitt on the depth chart.
