The Daily Mail reported that the 36-year-old had turned down an offer of a £5,000 appearance bonus and just £100 per week if he did not play.
But Fowler, who has been without a club since leaving Thai side SCG Muangthong United in January, spoke out on his Twitter account.
"Actually it was £90, but would need to play full 90 (minutes) to get full appearance bonus...," he tweeted.
Seasiders boss Ian Holloway claimed on Wednesday that he would be disappointed if the deal could not be completed.
He said: "Unless I can get things done and a deal done in a slightly different way, then he won't be coming. If it doesn't happen, I'll be disappointed, but such is life."
