SOUTH BEND, Ind. -- Notre Dame defensive lineman Tony Springmann missed practice Saturday and was seen wearing a large knee brace, and coach Brian Kelly expressed concern about the junior's status.
"At first glance -- any time there's a knee involved, you're always concerned, but I can't give you any definitive information," he said.
Springmann will undergo an MRI to clarify his status, but he's been ruled out at least for Aug. 31's season opener against Temple.
Running back Will Mahone suffered a high ankle sprain and was on crutches wearing a walking boot. His status for the Temple game is up in the air as well, although Kelly said the sophomore made progress working out in the pool before practice Saturday.

Freshman linebacker Doug Randolph will undergo shoulder surgery on Tuesday to correct a pre-existing condition and is out for the season. Safety Nicky Baratti will also undergo season-ending shoulder surgery Tuesday.
Offensive linemen Chris Watt and Conor Hanratty will be back and ready for Temple, Kelly said. Wide receiver Daniel Smith is expected to be cleared to play next week, while offensive lineman Colin McGovern was cleared for action Saturday.
Running back Cam McDaniel, who infamously ran the wrong way into a gauntlet machine this week, wasn't in pads for practice, but his situations wasn't addressed by Kelly, who's tried to make it a point only to discuss significant injuries in fall camp.
Lastly, running back Tarean Folston wasn't with the team due to a death in the family.
