Fulham are dealing in 36 year-old Finn Jari Litmanen.
Hodgson said: "Jari finished his contract last year and had operations on his ankle and his Achilles tendon and is probably the fittest he has been for years.
"I said to him that before you sign a long contract elsewhere, wouldn't you like to come and play for us until the end of the season. Luckily for me he said 'yes'. It is a bonus to have a player like him.
"Although he has not played much football lately, you never forget how to play football, and when you are as physically fit as he is going to be, what's to say he won't come in here and do a great job for us."
