(Update: RUGBYMag.com has learned the regional sites for DI-AA and DII men will be in Madison, Wisc., Knoxville, Tenn., Palo Alto, Calif., and Hanover, NH. Which regionional brackets will be where has yet to be confirmed.)

USA Rugby is expected to announce the sites and dates for the spring college and club national championships later today. The all star championship information will come later. 

The DI-A, boy's high school and boy's U19 national championships are expected to be at Rio Tinto in Sandy, Utah May 18-19. The men's DI-AA and DII college championships may also be in Sandy. 

The women's championships; high school, DI and DII college, are expected to be at Steuber Stadium in Palo Alto, Calif. May 11-12. 

The sites for the college rounds of 16 and eight will be unveiled later today, as well. Those are expected to be on campuses across the country, as they were for men's DI last year, with teams from the four regional brackets playing within that geographical region.

The DI-A quarterfinals are likely going to be on the campus of the higher seed, as they were in 2011. The semifinals, which were a part of Cal's exiting gripe, may move from a central location to more geographically sensible locations, as well.

The men's club final four will again be at Infinity Park in Glendale, Colo. The sites for the rounds of 16 and 8 are also to be named Friday.
