SOUTH BEND, IN – OCTOBER 28: Durham Smythe #80 and Cole Kmet #84 of the Notre Dame Fighting Irish celebrate after scoring a touchdown in the first quarter against the North Carolina State Wolfpack at Notre Dame Stadium on October 28, 2017 in South Bend, Indiana.

But apparently Kmet is made of much tougher stuff than we thought.Speaking to the media on Wednesday, Kelly revealed that Kmet is already back to catching footballs. Kmet broke his collarbone earlier this month, and as One Foot Down noted, it usually takes 6-8 weeks to heal.Whether or not Kmet is actually game ready though remains to be seen.Kmet is in line to start at tight end, replacing Alize Mack, who’s off to the NFL this fall. Last season Kmet had 15 receptions for 162 yards in nine games played. Brian Kelly says Michael Young underwent surgery to repair his broken collarbone.Kelly: “How long does it take for a bone to heal?”Reporter: “I don’t know.”Kelly: “I don’t know either.”Adds Cole Kmet is catching footballs already.— Pete Sampson (@PeteSampson_) August 21, 2019Nevertheless, Kelly does intend to utilize two tight end sets a little more often this coming year.Kelly says that while Cole Kmet is out there will still be some 2-TE sets, but they will be more situational.— Sean Stires (@SeanWSBT) August 21, 2019While Cole Kmet gets to game fitness, redshirt freshmen Tommy Tremble and George Takacs will presumably be utilized more.The Irish have dealt with plenty of injuries this summer, but Kmet’s is among the more impactful.If he can get back on the field in time for their game against Georgia, maybe Notre Dame has a chance to make some serious noise this year.
