Former Maryland quarterback Danny O?Brien has scheduled a visit to the University of Wisconsin this weekend, a UW source confirmed on Tuesday. O?Brien visited Penn State last weekend, according to FightOnState.com, and Mississippi on Monday, according to CBSSports.com. He has two years of eligibility remaining and because he will graduate this spring, he will be able to play during the 2012 season as long as he enrolls in a graduate program not offered at Maryland.
