U.S. Davis Cup captain Jim Courier plans to face No. 1 Novak Djokovic and Serbia in the quarterfinals with the same group - Sam Querrey, John Isner, twins Bob and Mike Bryan - that beat Brazil in the first round.

The United States hosts Serbia in Boise, Idaho, on April 5-7. The matches will be played on an indoor hard court.

Courier won't officially announce his roster until 10 days before facing Serbia. He said Wednesday that "assuming everyone's healthy, I think we'll field the same squad as we did" during a 3-2 victory over Brazil at Jacksonville, Fla., last month. Querrey beat Thiago Alves in the final match.

Courier says he's still trying to decide exactly how slow a surface to use in Boise.
