Eoin Bradley is disappointed with his exclusion from Derry football's provisional training panel for 2016.
New manager Damian Barton told BBC Sport NI last month he wanted Bradley in his squad but was not sure it would be possible given his Irish League soccer commitments with Glenavon.
Bradley's name was not included among the 43-man panel announced on Tuesday.
"So I'm not in the top 43 players in Derry.. I'll have to work harder," he said on Twitter.
After his appointment as Derry manager, Barton described Bradley as a "fantastic footballer and fantastic talent" but indicated he would not tolerate the Glenullin continuing to play both soccer and gaelic football.
"It's a very demanding environment in terms of fitness levels. People have got to be prepared to make sacrifices," he told BBC Sport Northern Ireland.
"It's very difficult to go back-to-back (in terms of playing matches) on consecutive days and I'm sure Eoin would concur with that.
"Everybody has commitments. Other people will have to fall into line. I'm hoping Eoin is available as well."
Bradley, who recently scored an Irish Premiership hat-trick for Glenavon against Ballymena, was omitted from the Derry squad by previous manager Brian McIver in 2014 due to his soccer commitments, but was recalled for the 2015 season.
