Benjamin Koyack KOY-ack; born April 9, 1993) is an American former professional football tight end.

[17] Koyack impressed team representatives and scouts in practice while working with Tennessee Titans tight ends coach Mike Mularkey.

[18] On January 24, 2015, Koyack played in the Senior Bowl for Tennessee Titan's head coach Ken Whisenhunt's North team and caught two passes for 19-yards and a touchdown.

He caught a 10-yard touchdown reception on pass from Oregon State quarterback Sean Mannion in the second quarter of the North's 34–13 victory over the South.

[22] At the conclusion of the pre-draft process, Koyack was projected to be a fourth or fifth round pick by NFL experts and scouts.

[27] Throughout training camp, he competed against Clay Harbor, Nic Jacobs, and Connor Hamlett for a roster spot.

The Jaguars opted to have only four tight ends on their active roster, including Marcedes Lewis, Julius Thomas, Nic Jacobs, and Clay Harbor.

[31] He competed with Jacobs, Braedon Bowman, and Neal Sterling throughout training camp for a roster spot.

He made the active roster and was named the backup tight end behind Lewis and Thomas to start the regular season.

[32] He made his professional regular season debut in the Jaguars' season-opening 27–23 loss to the Green Bay Packers.

[39] Although the Jaguars traded Thomas to the Miami Dolphins, Koyack still faced competition for the second tight end position from newly acquired free agent Mychal Rivera.

Marrone named him the Jaguars' second tight end behind Lewis to start the season after Rivera was placed on injured reserve due to a lingering hand injury.

[45] On January 7, 2018, Koyack caught his first career postseason touchdown catch in a 10–3 victory over the Buffalo Bills in the Wild Card Round.

[52] He was re-signed on October 9, 2019, after starting tight end, James O'Shaughnessy, suffered a season-ending torn ACL in a Week 5 loss to the Carolina Panthers.
