As noted last night on Observer radio, Taz did not come to Nashville this past week to do voiceovers for the Impact show that will air on Friday. This was during the period when TNA was late in paying him and it was said that he refused to go to Nashville until his check arrived.
On Friday's show, Matthews will be doing the commentary solo.
It is unclear what his future is with the company other than those very close to the situation confirm it appeared to be in question.
Taz has since removed all references to TNA on his twitter account.
