Cameron Fanning, 21, pleaded guilty to inflicting grievous bodily harm on the woman. It happened on June 15, 2019.
Fanning, of Sandpits Avenue in Ludlow, has previously admitted damaging property during the incident, but yesterday at Shrewsbury Crown Court he also pleaded guilty to the assault.
The hearing was adjourned so that reports can be completed on Fanning before he is sentenced. A date is set for March 16 at the same court.
