Jackson tried to return to the game but lasted two plays and left and didn't return. Perhaps it's a good sign he tried to go, but as the story said, he's a key element to the offense because of his deep threat ability and is potentially the biggest loss of the three if the injuries are multiple weeks.
Meanwhile Jeffery missed the final three quarters of the game and it's not clear how serious his injury is. If these guys miss extended time, Hollins, Arcega-Whiteside and Agholor are next up. Agholor is a potential deep-threat fill-in for Jackson but isn't on the same level.
PHI TE Dallas Goedert - Week 2 Fantasy Football Outlook
Week 2 at Atlanta
Dallas Goedert is caught in a tough spot because of all the talent in Philadelphia. He was as limited to three targets Week 1 which produced two catches for 16 yards. He will have days like this with a big day sprinkled in.
For now, he is depth on your roster as he rates a low-end TE2. He will only increase those numbers if something happens to starter Zach Ertz but until something like that happens, you might want to consider other options for the bench.
