Going the other way is Seol Ki-Hyeon. The South Korean leaves the Madejski in a permanent move to West London.
Director of Football Nick Hammond said, "We are extremely pleased to be signing a very talented England Under 21 international (Rosenior), who has significant Premier League experience but is also still only 23 years old.
"Seol's impact on the team was very significant in the early months of last season, and played an important role in establishing us in the Premier League during those important opening weeks. We wish him well at Fulham."
