Scrum-half Luke Baldwin has joined Harlequins from Worcester Warriors on a short-term loan.
Baldwin, 28, has been brought in following injuries to Danny Care and Charlie Mulchrone.
Quins boss Paul Gustard said: “I am delighted Balders has joined us. He will strengthen an area where we currently have a few injuries and lack of availability.
“Luke is a quick, running nine, who has a strong core skill-set which I am sure our supporters will look forward to seeing.”
Baldwin said: ”I am delighted to be joining Harlequins and look forward to helping them during this excellent season they are having.”
“I have an enormous amount of respect for Gussy and the work he is doing at the Club and I can’t wait to get started.”
