Pline was waived by the 49ers on Tuesday.
Pline joined the 49ers as an undrafted free agent out of Furman, but he was released along with fellow tight ends Logan Thomas and Eric Saubert as part of the team's final roster cuts Tuesday. With these three gone, Jake Tonges is currently set to serve as the lone backup behind starter George Kittle. Pline will now be subject to waivers, and, if he goes unclaimed, he'll be free to sign elsewhere ahead of the regular season.
