|Pops Mensah-Bonsu will not be wearing the Great Britain vest this summer|
The hopes of Great Britain to follow up on the London Olympics with a successful EuroBasket 2013 campaign had already been severely weakened in July, when it was confirmed that neither of Luol Deng or Joel Freeland will board the plane to Slovenia.
Following the withdrawal of the Chicago Bulls forward and the Portland Trail Blazers center, another key member of the national team, Pops Mensah-Bonsu, has announced his decision to not suit up for Great Britain at the upcoming show-piece event.
"Hurts my heart that I am not playing but I have my reasons! Trust me," the athletic big man wrote in a post on social network twitter on Tuesday.
Mensah-Bonsu, who averaged 11.5 points and 7.2 rebounds for Great Britain in last summer's Olympics, missed the biggest part of the last club season with an injury.
He returned to action in the spring with Cajasol Sevilla in the Spanish Liga Endesa and then joined EA7 Armani Jeans Milano, until the end of their Italian Serie A play-offs campaign.
Great Britain commenced preparations last Friday in London but Mensah-Bonsu was understood to have been granted permission to join training camp next week.
He tweeted his decision though upon his return from a trip to Ghana, where he took part in the NBA's Africa camp.
Great Britain were drawn in First Round Group A, together with Israel, Germany, Ukraine, Belgium and France.
MUSLI WILL WAIT FOR EUROBASKET DEBUT

decade, will not make his first appearance in a major tournament with the senior Serbian national team at EuroBasket 2013.
Serbia head coach Dusan Ivkovic decided on Tuesday to cut the young center from his preliminary roster for the big event.
"Musli did an excellent work training camp during the past month, but the competition at the center position is very strong on our team," Ivkovic explained.
"Since we have five good players at that position, we decided it would be better for him if he continued the off-season with his club [Partizan Belgrade]."
Musli has only suited up for the senior Serbian side during last summer's Qualification Round for the EuroBasket.
The 2.12m center featured in four of their ten games in the competition and averaged 5.8 points and 4.5 rebounds per encounter.
Serbia were drawn into First Round Group B and will go up against Bosnia and Herzegovina, Montenegro, F.Y.R of Macedonia, Latvia, and Lithuania.
