Can some one tell me if its legal for Texas Workers Comp to force someone to work for another company while under light duty orders?

By forced I mean that she is being told that since she is on light duty work she can work for another company and if she doesnt she will be denied workers comp

The workers comp insurance is telling her she has to go work for this other company that they are telling her to go to since she cant do her regular job and is on light duty

Workers comp actually set up an interview for her with totally different company and told her she had to go to it
