At a wrestling match

Garth is fighting his opponent.

The battle lasted for a while. Oh no. What's going on? Why is Garth without strength?

Garth had fallen to the ground. His opponent went down to get something under the Stage, which was the ropes, rags and chair. He lifted Garth to his chair and began tied him up with the chair.

Garth struggled to keep his opponents from binding him with rope. But he can't get free form bindings of his rival, because he lose his strength. Then his rival stuffed a rag into Garth's mouth and gagged with cloth. “Mmmmmm! Mmmmphmm! Mmmrrm! Mmmhmmm! Mmmphh!” Garth struggled. “If you can break free I will forfit the match for you AHAHAHAHAHAHAHAHAHAAHAHA" his rival said and laughed.

Garth struggles, but he can't break free. Something makes him weak. What happened, Is the his rival cheated? What will the match be like next?
