Christian Malcolm could make his final track appearance in Wales at the Welsh Athletics International at Cardiff on 15 July.
The sprinter, 35, is considering retirement after missing out on selection for the Commonwealth Games.
Malcolm failed to reach the 200m final at the Welsh Athletics Championships in Cardiff after registering a poor time.
He finished third in the heats in 21.96 seconds, with the A standard being 20.50secs.
The Newport sprinter has struggled with injuries and a problem with an Achilles tendon saw him miss the whole of last season, including the World Championships in Moscow.
Malcolm has competed at four Commonwealth Games, winning 200m silver in Kuala Lumpur in 1998 and a bronze in the same event in Delhi four years ago.
He is expected to run in the 4 x 100m relay at the Cardiff event, which will feature many other stars who will be Commonwealth Games-bound, including Wales captain Aled Sion Davies.
The Welsh Athletics International will bring together Wales' leading stars to compete against athletes from countries including Australia, Bahamas, Greece, Jamaica, New Zealand and USA.
Team Wales captain Davies, the double world champion and double Olympic medallist, is a guest in the men's discus competition, alongside Glasgow 2014 medal hopeful Brett Morse and decathlete Curtis Matthews, another who is going to this summer's Games.
