The 35-year-old centre will play his final game for Ireland this Saturday when they travel to Paris to face France.
And after playing alongside O'Driscoll for club and country, Reddan is desperate to ensure his team-mate gets the send-off he deserves.
"It was a great occasion, but the players have to pay their respects in terms of delivering in Paris for him," said Reddan.
"It was right to have it: these moments can pass you by if you don't emphasise them.
"Now we as players have to deliver, and give him a pat on the back in a different way, and produce a huge performance in France to give him a proper and well-deserved send-off.
"The temptations are there for people outside the group to go over the top on a polished performance, but there's no way we're seeing ourselves as favourites over there."
