According to the Barrington (R.I.) Times, 6-foot-8 power forward Cedric Kuakumensah gave Brown a verbal commitment on Sunday.
The Worcester, Mass., native chose the Bears over Holy Cross and Pennsylvania.
"It's a proud day for us and for Cedric," St. Andrew's head coach Mike Hart told the paper. "For one of our kids to go to Brown shows they're finally starting to get it. It's not all about basketball. It's about getting an education."
Kuakumensah is the first recruit for Brown in the 2012 class.
