21.—(1) Subject to paragraph (2), a person entitled to a transitional award of long-term incapacity benefit in respect of a personal injury of a kind mentioned in section 94(1) of the 1992 Act shall cease to be so entitled when the incapacity for work is no longer as a result of that injury.
(2) Where a person’s entitlement to a transitional award of long-term incapacity benefit ceases as a consequence of paragraph (1) and no more than 57 days after entitlement to that award ceases he becomes incapable for work as a result of the same personal injury in respect of which the transitional award of long-term incapacity benefit was payable, he shall be entitled to benefit at the rate at which the transitional award of long-term incapacity benefit would have been payable had he not ceased to be so entitled; and these Regulations shall apply as if the award of incapacity benefit were a transitional award of long-term incapacity benefit.
