Linebacker Darius Fleming told WSBT he has been invited to the event, held Feb. 22-28 in Indianapolis, and so has cornerback Robert Blanton.
Fleming said he was invited via email, which he received Friday, the day after the Irish lost 18-14 to Florida State in the Champs Sports Bowl.
Fleming said he will train at EFT Sports Performance in Northbrook, Ill., the same place former Irish running back Robert Hughes trained last year before the draft.
"I'm just going to train from this point on," Fleming said. "Rest my body up, try to lose a couple pounds, and just try to get ready for that day."
The complete list of invited players will be released in late January, according to the Scouting Combine website.
The website draftcountdown.com lists Fleming as the 11th-best outside linebacker in the draft, and Blanton the 18th-best cornerback. The website nfldraftscout.com projects Fleming to be a fifth round pick and has Blanton going somewhere in the fourth or fifth round.
