With the Hornets light up front, they will be happy to call on the services of Welbeck as soon as he is 100 percent fit.
"Danny is a really good player and a big character in our dressing room," said manager Nigel Pearson to reporters.
"His return gives us another option. His track record is excellent and he has had a great career. He is the type of player that really wants to be back in the fray.
"I am delighted that he has overcome the problem he has had. I know he has had a few injury issues but he works exceptionally hard and it is great to have him available."
