GREEN BAY – Packers tight end Josiah Deguara suffered a knee injury Monday night against Atlanta that's believed to be significant, according to Head Coach Matt LaFleur.

The rookie third-round pick out of Cincinnati played well in his debut against Minnesota in Week 1, catching a pass for 12 yards and factoring into several key plays as an H-back and move tight end.

Deguara missed the next two games with an ankle issue but returned to play against the Falcons. He was involved in eight snaps before injuring his knee on a punt in the final minutes of Green Bay's 30-16 victory.

"Unfortunately, it looks to be a pretty bad one," said LaFleur of Deguara's injury. "I hurt for Josiah. I love what he's all about, the mentality he brings and certainly somebody we were really excited about.

"It's been a little bit of a rollercoaster in terms of I thought he had a great game vs. Minnesota in Week 1 and then he goes out with the ankle injury. It's just been tough, but we expect him to bounce back from it. We still think he has a really bright future in this league."

The Packers recently promoted versatile tight end John Lovett from the practice squad to fill in as an H-back during Deguara's previous absence. Jace Sternberger also played the role late last season when fullback Danny Vitale was out with a knee injury.
