The Giro d'Italia will take place without a British rider for a second successive year.
Two Irishmen, Philip Deignan and Nicolas Roche, are slated to start the year's first Grand Tour, which begins in Apeldoorn, Holland with a 9.8-kilometres time-trial on Friday.
Alex Dowsett had been expected to start for Movistar, but the Commonwealth Games time-trial champion has undergone surgery to remove a plate and screws on his collarbone.
Team Sky have eight Britons on their 29-rider roster, but none are in the squad for the Giro, which finishes in Turin on May 29.
Deignan and Roche were on Tuesday named in Team Sky's nine-man line-up, as support riders to Spaniard Mikel Landa.
Landa and Vincenzo Nibali (Astana) are the favourites for the pink jersey.
Nairo Quintana (Movistar) and Alberto Contador (Tinkoff), the winners in each of the last two years, do not start as July's Tour de France is their priority this year.
Kirsten Wild took victory in the women's Tour de Yorkshire after Lizzie Armitstead's gutsy bid for glory fell short in Doncaster.
Wild (Team Hitec-Products) won the bunch sprint ahead of Wiggle High5's Lucy Garner after the peloton had chased down world champion Armitstead and two fellow escapees inside the final three kilometres of the 136.5km route.
Wild collected around £15,000 as a prize fund totalling £50,000 was handed out - a record in women's cycling.
Unfortunately, coverage of the race ran into problems as a relay plane was grounded with a technical fault and so no pictures could be broadcast on ITV4.
Cyclist Simon Yates has not received a suspension after failing a drugs test as his Orica-GreenEdge team try to clear up an administrative error.
Yates tested positive for terbutaline, which is being blamed on an inhaler he was using for his asthma, as his Australian team take full responsibility for the failed test.
The Union Cycliste Internationale (UCI) confirms that British rider Simon Yates has been notified of an adverse analytical finding of terbutaline in a sample collected in the scope of an in-competition control on March 12, 2016.
As per the UCI's anti-doping rules, such substance does not entail the imposition of a provisional suspension.
The rider has the right to request and attend the analysis of the B sample.
At this stage of the procedure, the UCI won't comment any further.
Shane Sutton has resigned from his role as Technical Director at British Cycling following discrimination claims.
The Australian denied all allegations of wrongdoing after the governing body launched an independent investigation into allegations he told a female cyclist to "go have a baby".
Sutton had been suspended by British Cycling on Tuesday after the instigation of the internal review.
Today starts the 100-day countdown to the Olympic and Paralympic Games. It is absolutely crucial that, as our athletes begin their final preparations for Rio, they are able to do so free of distraction.
The developments over the past few days have clearly become a distraction. It is for this reason, and having spoken to friends and family, that I believe it is in the best interests of British Cycling for me to step down from my position as technical director.
It is important that the review announced by British Cycling and UK Sport now takes place, and I will obviously co-operate fully with this. I have made clear that I reject the specific claims that have been made against me in recent days, and I look forward to taking a full part in the review process so I can respond to the allegations in detail.
Cycling is my passion and I have always worked to get the very best out of professional athletes. I am proud of what British Cycling has achieved and I am excited by the potential of the team for Rio. They will always have my full support.
The technical director, who refutes the allegations, has been accused of sexism and calling Paralympic cyclists derogatory names.Read the full story ›
Belgian rider Femke Van den Driessche has been suspended for six years by the UCI in the first case of motorised doping in cycling.
Disciplinary proceedings began in March after the 19-year-old allegedly used a bike containing a motor at January's UCI Cyclo-cross World Championships in Belgium.
The UCI announced on Tuesday that its disciplinary commission banned Van den Driessche for violating its rules relating to "technical fraud" while she has also been fined 20,000 Swiss Francs (£14,000) and been ordered to pay legal costs.
A Union Cycliste Internationale statement read: "Ms Femke Van den Driessche is found to have committed a violation of art. 1.3.010 in combination with art. 12.013bis (technological fraud) of the UCI Regulations.
"Ms Femke Van den Driessche is suspended for a period of six years starting from and including October 11, 2015 and ending on October 10, 2021."
UCI president Brian Cookson said last month that the world governing body would request the toughest possible sanctions.
Bikes have been scanned by the UCI at major competitions across all disciplines, including the Tour de France, in recent years following rumour and speculation regarding motors hidden in frames.

Emma Pooley will race alongside world champion Lizzie Armitstead in the Great Britain team at the Asda Women's Tour de Yorkshire on April 30.
Pooley retired from professional cycling following the 2014 Commonwealth Games to turn her attentions to long-distance triathlon and duathlon. She won the long-distance duathlon (cycling and running) world titles in 2014 and 2015.
She has been tempted to return to cycling by the undulating time-trial course for the Rio Olympics, where she is also expected to be selected in support of Armitstead for the road race.
The 33-year-old, who won Olympic time-trial silver in Beijing in 2008, will line up alongside Armitstead for the 135-kilometres race, which begins in Otley and finishes in Doncaster.
She said: "I'm really looking forward to joining up with my Great Britain team-mates for the Women's Tour de Yorkshire race and I'm looking forward to racing on the road again."
British Cycling technical director Shane Sutton said: "Emma is a phenomenal athlete and will be an asset to the team. Emma has committed herself to training for the Olympic time-trial event in Rio, and we appreciate and support the sacrifice she is making to be in the best possible shape for this event."
Italian Luca Paolini has been suspended for 18 months following his positive test for cocaine at the 2015 Tour de France, the UCI has announced.
Paolini was provisionally suspended on July 10 after testing positive on July 7 for a metabolite of the recreational drug after the cobbled fourth stage of the Tour.
The case was heard by the UCI anti-doping tribunal, which ruled the 39-year-old's positive test was "non-intentional" and, if the 18-month ban is applied from the date of his positive test, which is ordinarily the case, he will be eligible to return in January 2017.
The Katusha rider said in Gazzetta dello Sport he sought help for addiction to sleeping pills after his positive test for cocaine.
A statement from the UCI, cycling's world governing body, read: "The anti-doping tribunal found the rider guilty of a non-intentional anti-doping rule violation (presence of a cocaine metabolite - benzoylecgonine) and imposed an 18-month period of ineligibility on the rider."
The full decision was to be published on the UCI website.
