PHILADELPHIA (973espn.com) — The Indianapolis Colts tried to sign Nate Sudfeld off the Eagles' practice squad this week and now you understand why.

The Colts officially shut down superstar quarterback Andrew Luck for the entire 2017 season Thursday, placing the former No. 1 overall pick on injured reserve.

Luck underwent surgery on his throwing shoulder back in January and the early indications were that he would be back for the start of the 2017 campaign, something that obviously never materialized.

"I wish I was better and 100 percent this season, but that's not the case," Luck told the team's website. "I know I'll be better from this. I know I'll be a better quarterback, teammate, person and player from this, and I'm excited for the future."

Luck was able to return to practice for a brief period early last month but suffered a setback and received a cortisone injection to relieve persistent soreness in the shoulder. When that didn't work Indy decided to shelve the face of the franchise.

Colts general manager Chris Ballard, however, said the new plan is rest and rehabilitation, not a second surgery and claimed that the outcome here did not mean Luck's career is in jeopardy.

"The shoulder is subjective and after a surgery everybody is different," Ballard claimed. "Everybody rehabs in a different way. So we're going to shut his throwing down and continue rehab. We're going to continue hard rehab. We think for the long-term interest of Andrew, this is the best course of action."

Second-year quarterback Jacoby Brissett is the current starter in Indy and the Colts wanted to bring on Sudfeld, who played in college at the University of Indiana, as depth but the Eagles nixed that by promoting the lanky QB to their 53-man roster on Wednesday, waiving defensive tackle Justin Hamilton to make room.

The Eagles were already paying Sudfeld ($540,000) far more than an average practice squad player ($122K).
