Evidence of Settlement

T.C.A. Sec. 29-11-105 (b) says as follows:  "No evidence of a release or covenant not to sue received by another tort-feasor or payment therefor may be introduced by a defendant at the trial of an action by a claimant for injury or wrongful death, but may be introduced upon motion after judgment to reduce a judgment by the amount stipulated by the release or the covenant or by the amount of the consideration paid for it, whichever is greater."

Does this prohibit a defendant from introducing evidence of a settlement with another defendant but permit a plaintiff to do so (at plaintiff’s option)?  If so, can the plaintiff introduce the fact of settlement, the amount of the settlement, or both?
