De Grasse developed right groin tightness after Diamond League race in Switzerland
Sprinter withdrew from Sunday's 100m in Stockholm, where Aaron Brown was 5th
Andre De Grasse is not dealing with an injury, the Markham, Ont., sprinter's agent says, but did experience right groin tightness "hours after" Friday's sixth-place finish in the men's 200 metres at the Athletissima track and field meet in Lausanne, Switzerland.
The six-time Olympic medallist pulled out of Sunday's 100 at the BAUHAUS-galan competition in Stockholm for precautionary reasons.
"Andre does not have an injury. He had a bit of tightness in his groin and decided not to take a risk," Paul Doyle of Georgia-based Doyle Management Group told CBC Sports on Monday. "He's fine and even did a workout [on Sunday] without any discomfort."
Doyle was in Stockholm with De Grasse and the latter's physiotherapist who assists coach John Coghlan at the runner's daily training sessions.
Sunday's race was billed as a much-anticipated showdown with 4x100 relay teammate Aaron Brown of Toronto at the seventh stop on the Diamond League calendar.
Brown was fifth in Lausanne and Sweden, where he stopped the clock in 10.27 seconds, powering through the wet conditions at Stockholm Olympic Stadium. The points earned places him third in this season's DL standings.
South Africa's Akani Simbine prevailed in 10.03, followed by Reece Prescott of Great Britain and Joshua Hartman of Germany.

Fellow Canadian Jerome Blake was third in the national 100 with a time of 10.30 in a race that doesn't count toward Diamond League points.
The Kelowna, B.C., native finished behind the victorious Hartman and South Africa's Ben Richardson.
Diamond League action resumes July 16 in Chorzów, Poland, just over a month from the Aug. 19-27 World Athletics Championships in Budapest, Hungary.
Protesters disrupt 400m hurdles race
Olympic champion Karsten Warholm of Norway won his 400 hurdles race and then turned to join in the crowd booing environmental protesters who disrupted his event near the finish line.
Three people kneeled on the track about eight metres from the line holding two banners that spanned from Lanes 1-6, forcing runners to break through them. No athlete appeared to be hurt.

Warholm, running in Lane 8, had no barrier in his way though seemed distracted, with a fourth apparent protester squatting in Lane 7 seeming to photograph the incident.
He was visibly angry with the protesters as they were led away while spectators booed.
Warholm's winning time on a cool, rainy evening was 47.57 seconds, well outside his 45.94 world record set at the Tokyo Olympics two years ago.
An unusual evening's work for Warholm included warming up in a parking garage in downtown Stockholm so, the athlete said later, he could arrive "dry and warm coming to the start."
Duplantis short of pole vault world record
The rain wreaked havoc with numerous events, particularly the much-anticipated men's pole vault featuring local hero Armand Duplantis.
The event was delayed more than two hours due to safety concerns. Fans stuck around to watch more than an hour after every other event had finished and vaulters cradled cups of tea to keep warm.
Duplantis, the Olympic and world champion, cleared 6.05 metres on his first attempt to win. He then missed on three attempts at 6.23, which would have topped his world record of 6.22.
