Tynes, who is battling a staph infection, said he believes he should be put on injured reserve instead.
"This whole thing is wrong," Tynes told FoxSports.com. "My biggest emphasis is I don't want this to happen to any current or future player. I'm going to fight this thing as long as I have to, because this team should not be allowed to do this to players.''
Tynes acknowledged that the Bucs have agreed to pay his $840,000 base salary, even though players on the NFI list are not required to be paid. But the veteran is unhappy that his NFI status will not allow this to count as an accrued season toward his retirement pension.
It's not clear how Tynes, who signed with the Bucs in June, came into contact with MRSA. Guard Carl Nicks also has a staph infection, and the team has said it has had its facility treated twice to prevent further outbreak.
"If I drop a 45-pound plate on my foot while lifting weights in the weight room at the facility, it's IR,'' Tynes told FoxSports.com. "So I just don't understand how my situation is any different. I went to work, I kicked, I practiced, I cold-tubbed, I hot-tubbed, I showered for all those days there. I come up with MRSA, and it's a non-football injury? They're basically trying to exonerate themselves of this, and I'm not going to allow it to happen."
