London Welsh captain Tom May says Saturday's final Premiership game will be "strange" but he is ready to retire.
May, 36, will quit after the weekend's fixture against Saracens at the Kassam Stadium in Oxford.
The centre, formerly of Newcastle and Northampton, is set to make his 247th top-flight appearance - third on the all-time Premiership list.
"It's going to be strange waking up on Monday morning and not having a job," May told BBC Radio Oxford.
"I'm trying to enjoy every last session and approach the game in a positive manner. I think it'll be on my mind. I'll try to put it to the back of my mind and enjoy the occasion."

Having begun his career at Newcastle, he went on to play for Toulon and Northampton before joining Welsh in 2013.
"My body is killing me," he said. "Monday to Friday is tough and it makes it really difficult physically.
"Seventeen years is a long time and I want to quit while I'm ahead so that I make the decision and no-one else does. Now is the right time."
He said his two caps for England, his club success and his place on the Premiership appearance list are career highlights.
"Winning two trophies with Newcastle and winning something here last season all stand out," he said.
May has already made plans for what to do after ending his playing career.
"I'm running a grassroots rugby scheme, doing some media, some speaking, trying to open a gym," he said. "I'm doing some player management as well as playing some non-professional rugby. I'm busy. I haven't had time to think about retirement.
"London Welsh gave me an opportunity to play. I'm glad I've experienced this year with these guys. Hopefully I've helped them get through the poundings we've had. It's been tough but I've enjoyed it."
