Vance McDonald in concussion protocol still.

Related players: Nick Vannett

McDonald left in the second half of Week 14's game with the Cardinals. Vannett will take over for McDonald if he can't go in Week 15 against the Bills.

The Pittsburgh Steelers traded a 2020 fifth-round pick to the Seattle Seahawks for TE Nick Vannett.

The Steelers are weak at the tight end position and Vance McDonald has a hurt shoulder to go along with plenty of other ailments in his past that make getting 16 games out of him a challenge. Even if McDonald can't play, Vannett would likely split work and we've yet to see this Steelers offense without Ben Roethlisberger show much fight.

The Seahawks have re-signed Jaron Brown and placed Ed Dickson on Injured Reserve.

Brown was released but quickly brought back to the roster and is expected to still see time in 2 WR sets, especially with Metcalf battling knee issues. Meanwhile, Dickson's move to IR makes Dissly and Vannett next up on the depth chart. No one is really a safe play outside of Lockett, however, and we first have to see how the rest of the targets shake out.

Seattle has six tight ends on its roster heading into camp — fewer than it usually has, which is likely in large part because of Fant. Those six are: Will Dissly, Ed Dickson, Jacob Hollister, Nick Vannett, Tyrone Swoopes and Justin Johnson, the latter an undrafted free agent out of Mississippi State.

When I did a 53-man roster projection following minicamp, I kept three tight ends — Dissly, Vannett and Hollister.

Bob Condotta is the author and believes Dissly, who we have as the highest ranked Seattle TE, could end up on the PUP list to start camp and added the team will be patient with him and his patellar tendon injury. Hollister was acquired in a deal with the Patriots and the team seems high on him because of his speed. The story said Dickson will be 32 at the start of camp and the team could save $3.55 million by releasing him.
