Notre Dame coach Brian Kelly provided updates after practice Saturday on tight end Alex Welch and linebacker Danny Spond, who both suffered injuries during Wednesday's practice.
Kelly said Welch tore the anterior cruciate ligament in his right knee and is out for the season.
Kelly said Spond did not have a concussion or a head injury, but more tests will need to be run before the junior can fully participate in practice.
"We are going to do a little bit more work before we move any further, relative to contact and getting him on the field," Kelly said of Spond. "We've done a number of tests, and it's one of those things that we want to make certain before we put him back out on the field."
With Spond out, Kelly said Romeo Okwara and C.J. Prosise will be moved to the outside linebacker spot to work with Ben Councell. Notre Dame could also use Prince Shembo, who is at the other outside linebacker spot with Ishaq Williams, to fill in for Spond.
The Irish are also still in good shape at tight end, despite the loss of Welch.
Former Bishop Dwenger standout Tyler Eifert headlines the group, and Ben Koyack, Troy Niklas and Jake Golic are also expected to see plenty of playing time as the Irish will still plan to use two-tight end sets this season.
"We feel good that we've got depth at that position that we can get the job done," Kelly said. "That's not going to stop us from playing two tight ends this season."
