Philadelphia activated Jackson (knee) from the reserve/PUP list Wednesday.
Jackson will join the 53-man roster for the first time since tearing his ACL during the Eagles' 2021 regular-season finale. He'll likely operate in a rotational role behind Grant Calcaterra and Jack Stoll if he suits up Sunday in Indianapolis, but all three tight ends are candidates for increased roles while Dallas Goedert (shoulder) is on injured reserve.
