Grinnage was cut by the Jaguars on Monday, Daniel Popper of The Athletic reports.
Grinnage was let go by Jacksonville to make room for Ben Koyack on the 53-man roster. The depth tight end played well in limited rotational snaps, but was ultimately unable to stick with the Jaguars. He'll look to earn a depth role elsewhere in the league.
Grinnage (knee) is active Sunday against the Colts.
Grinnage has only been active three weeks this season, but had at least one reception in each of those contests. He's listed behind James O'Shaughnessy on the depth chart, however, with O'Shaughnessy set to suit up for the first time since Week 6.
