Kenwyne Jones has admitted his frustration at on-going speculation over his long-term Sunderland future.
Fresh question marks have been raised over Jones' future with Darren Bent due to join in a record-breaking deal.
The striker is expected to have a medical with the Stadium of Light outfit on Wednesday after Spurs wrapped up Peter Crouch's signature.
Bent's impending arrival has coincided with talk that Jones could leave, with Spurs previously being interested in his services.
However, the 24-year-old insists he is fully committed to the four-year contract he signed earlier this year.
"If I wasn't committed to Sunderland I don't think I would have just been away on pre-season for 10 or 11 days," said Jones.
"I signed a four-year contract in January and I'm committed to staying for that length of time, maybe more - you never know.
"I do get sick and tired of constantly hearing about this team and that team and me."
