The deal is done, and the ACC tournament is coming to the Barclays Center in Brooklyn for 2017 and 2018, a person with direct knowledge of the agreement told USA TODAY Sports.

The Barclays Center is expected to hold a news conference to announce the news on Wednesday.

Currently, the Atlantic 10 hosts its postseason tournament at the Barclays Center and had been under contract with the venue to host it there through 2017. The ACC will play its conference tournament in Greensboro, N.C., in 2015 and Washington, D.C., in 2016.​ But after adding new members this season (Syracuse, Pittsburgh and Notre Dame), the ACC had been eyeing New York City. Coaches and school officials have been talking about the possibility for more than a year. With Madison Square Garden locked up in a long-term deal with the Big East, the ACC turned its attention toward the Barclays Center.

The Atlantic 10 will move its postseason tournament out of Brooklyn for 2017-2018 and return to the Barclays Center from 2019-2021, according to the person with knowledge of the situation. The person also confirmed that there will be a series of ACC-A-10 doubleheaders at the Barclays Center.

The A-10 is looking at possibly moving its tournament to Washington, D.C., or Pittsburgh for 2017-18, another person with knowledge of the situation told USA TODAY Sports earlier this month.
