The Red Cross says fans put $40,000 in buckets as they entered Michigan Stadium this past weekend. University officials estimate another $10,000 was raised by program sales.
Members of the women's and men's swimming teams collected donations with a group of local Red Cross volunteers before the Wolverines played Northern Illinois on Saturday.
One anonymous donation was a wad of five $100 bills. The school will give the Red Cross $2.00 for every program sold for the season opener.
The Red Cross says the money will go toward providing shelter, food and mental health services for victims of Hurricane Katrina.
