The deal with the nine-year WNBA veteran was announced Tuesday.
Lennox was the leading scorer on the Atlanta Dream last season before being waived. She averaged 17.5 points and started 33 of 34 games for the expansion team that set a league record for losses in a season with 30, including 17 to start the season.
Lennox has also played for Minnesota, Miami, Cleveland and Seattle in her career. In 2004, she led the Seattle Storm to the WNBA title and was named MVP of the finals.
