Illinois guard Kendrick Nunn will not play Thursday at Michigan State and did not make the trip to East Lansing, a team spokesman told IlliniInquirer.com
Nunn stayed in Champaign to attend the birth of his first child.
Nunn is averaging 18.5 points per game, tied for most in the Big Ten along with Michigan State senior guard Denzel Valentine, who will sit out Thursday's game with a knee injury.
Illinois had a contingency plan in place to fly Nunn to East Lansing if the child arrived early, but that did not happen.
Illinois already is short-handed due to multiple injuries -- Mike Thorne Jr. (knee), Leron Black (knee), Tracy Abrams (Achilles) -- and senior guard Khalid Lewis will return tonight after missing two games with the mumps.
Illinois will have eight scholarship players available against MSU.
