Jake Butt suffered a torn left ACL during Thursday’s walkthrough practice, according to Mike Klis of 9News (on Twitter). Butt is done for the year and will be placed on injured reserve. 
It’s a crushing blow for Butt, who tore his right ACL twice while at Michigan. Through three games, Butt was making an impact, and had eight catches for 85 yards. He’ll now have to wait until September of next year to build on his progress.
Butt was the 145th overall pick in the 2017 draft, but offers far more upside than your average fifth-rounder. Before his second torn ACL suffered in the Orange Bowl, Butt had a chance to parlay back-to-back strong seasons into becoming a first- or second-round pick. Butt combined for 97 receptions and seven touchdowns during his final two years with the Wolverines and earned first-team All-America honors in each season.
Without Butt, top tight end Jeff Heuerman and backup Matt LaCosse will be relied on a bit more heavily. Fifth-round pick Troy Fumagalli is on IR with an abdominal injury, so the Broncos may look to sign another tight end this week.
They have tight ends from 4 Big Ten schools already so they might as well go for another
During a walkthrough? Now that’s bad mojo
I feel bad for the guy but “it’s a crushing blow for Butt” sounds hilarious lol
Don’t be so anal about their grammar.
I really thought Butt would explode this year.
Damn. This guy has had some tough luck on his knees. If he decides to come back I wish him great luck in his recovery.
