Bob and Mike Bryan were not on the entry list released for men's doubles at the US Open on Wednesday, possibly signaling the end of the 42-year-old American twins' record-breaking careers.

The Bryans won five of their 16 Grand Slam doubles titles together in New York, most recently in 2014.

Mike also won the 2018 US Open with Jack Sock when Bob was recovering from hip surgery.

Three-time US Open champion Kim Clijsters received a wild-card entry in doubles to go along with the one she got for singles as she makes her Grand Slam comeback.

The tournament begins singles competition Aug 31, and doubles on Sept 2. The doubles fields are being cut from 64 to 32 teams for women and men this year to reduce the number of people on site because of the coronavirus pandemic.
