Wrong team gets ball

[Jim Henry]

Situation….

Ref gives ball to wrong team (A) after time-out. Player A1 receives in bound pass and scores basket in A’s basket. Easy uncontested lay-up since most players were at the other end of court waiting for Team B to come into front court.

Meanwhile, Coach for Team B is screaming about the mistake and play continues like it would after any basket scored. What should be done? Correctable situation?
