TAMPA, Fla. – Tom Knight helped Notre Dame stop its slide in his first start this season.

Jerian Grant scored 18 points and Knight had 17 as No. 24 Notre Dame beat South Florida 73-65 on Saturday.

Knight, a 6-foot-10 senior, made the most of his chance as the Irish played without sixth-year forward Scott Martin, who is out indefinitely with a bad left knee. Knight had appeared in just 12 of Notre Dame’s first 19 games this season.

“I would have been shocked if he didn’t play well,” Notre Dame coach Mike Brey said. “He’s been around us for a while, so it’s nice. You lose a six-year senior, and we put in another senior who’s been in our program. Certainly helped us.”

Knight had never scored in double digits before, with his previous best being nine points against Sacred Heart on Dec. 19, 2011. He made 8 of 10 shots and pulled down seven rebounds Saturday.

“He’s just playing with confidence right now.” Grant said of Knight.

“A lot of people knew he had it. He’s knocking down shots, rebounding, blocking shots, so it’s definitely something we need the rest of the year.”

Eric Atkins added 13 points and Pat Connaughton contributed 12 for Notre Dame (16-4, 4-3 Big East), which had lost three of four, including a 63-47 loss to Georgetown last Monday.

Notre Dame forward Jack Cooley, who entered averaging 14.8 points, finished with six points and 14 rebounds.

Zach LeDay had 17 points and Anthony Collins added 12 for South Florida (10-9, 1-6).

Notre Dame used a 20-3 run to go ahead 48-40 with 13 minutes to play. Connaughton’s three-pointer broke a 40-point tie before Knight dunked and Grant connected on a three to make it 48-40.

“Sometimes I like to get up there and show (our coaches) I can,” Knight said. “It was nice to do that. And the dunk was obviously fun, too.”

Notre Dame outrebounded South Florida 34-17.

Note: ESPN announced Saturday that its “College GameDay” show will come to Notre Dame on Feb. 9 when the Irish play host to No. 5 Louisville at 9 p.m.
