Which 49ers players are on the bubble entering training camp?

49ers training camp bubble watch: Tight end

Lock: George Kittle

Strong bubble: Ross Dwelley, Tyler Kroft, Charlie Woerner

Weak bubble: Tanner Hudson, Jordan Matthews

Long shot: Troy Fumagalli

As far as the 49ers are concerned at tight end, there’s All-Pro George Kittle and then everyone else.

Kittle is expected to revert back into being one of the NFL’s best all-around weapons this season, yet the Niners don’t exactly have a clear-cut No. 2 option to support him despite years of trying to find one.

In theory, this job likely goes to the player who admirably did so back in 2020 when Kittle missed eight games, Ross Dwelley, yet a notable lack in production in both field time and targets suggests Dwelley could hit 2022 as a bit of an afterthought.

If San Francisco elects to keep four tight ends on its 53-man roster, though, Dwelley and run-blocking tight end Charlie Woerner should have little problem hanging around. And it’s possible the 49ers are hoping veteran tight end Tyler Kroft, who had 404 yards and seven touchdowns back in 2017, emerges as that complementary threat.

Kroft carries only $25,000 in guaranteed money, though, so he’s by no means a sure thing to make the regular-season roster, especially if a fringe tight end like Tanner Hudson or even Jordan Matthews, whom the 49ers also seem to inexplicably love, impresses more during training camp.
