The Briton blamed Sagan for elbowing him amid the run complete in Vittel.
Cavendish, 32, completed the phase in the wake of accepting restorative treatment for a few minutes, before going for a X-beam.
“I get on well with Peter and a crash is a crash yet I’m not an aficionado of him putting his elbow in,” said Dimension Data rider Cavendish.
Briton Geraint Thomas kept his general lead as Arnaud Demare turned into the main Frenchman to win a cluster dash arrange at the Tour since 2006.
Protecting champion Chris Froome stays second generally speaking, 12 seconds behind countryman Thomas.
The dash for the line was in full stream with Cavendish following Demare down the right-hand side of the street with the riders going at around 60km/h.
Sagan likewise moved on his right side to utilize Frenchman Demare as a lead-out man and, from cameras behind the race, appeared to flick an elbow out at Cavendish as the two struggled for space.
The camera edge from the front proposed Sagan was attempting to keep his adjust yet leaving Cavendish with no place to go aside from into the obstructions.
Cavendish, who has won 30 Tour de France stages – four behind the record-breaking record of Eddy Merckx – said Sagan apologized to him after the stage.
The Manxman landed intensely on the correct shoulder that he disjoined when he smashed out in front of an audience one of the 2014 Tour de France in Harrogate.
His correct hand was wrapped before he remounted his bicycle and accelerated over the line.
“I require fastens in a finger,” said Cavendish, who likewise had his correct arm in a sling after the stage.
“It’s something to do with the shoulder that I hurt in Harrogate. I’m not a specialist but rather I’m not idealistic.”
Slovakian Sagan remained upright to complete second on the stage, yet his exclusion implies his expectations of equalling Erik Zabel’s record of winning six progressive focuses order titles is finished.
The Bora-Hansgrohe rider said before his exclusion was declared: “He was digging out from a deficit. I didn’t have sufficient energy to respond and go left. He came to me and I needed to guard.”
Approached on the off chance that he had apologized for the crash, he stated: “Without a doubt, since it’s not decent to crash that way.”
Measurement Data donning executive Roger Hammond tweeted an overhead perspective of the episode with the words: “Makes a major crash at 1.5 go, elbows kindred rival in the head 300 meters… can just outcome in one choice. #Goodbye.”
The underlying stage comes about posted on the Tour’s site indicated Sagan had been docked 30 seconds and 80 focuses, however Dimension Data challenged that choice.
After a survey, Philippe Marien, leader of the race commission, stated: “We’ve chosen to exclude Peter Sagan as he jeopardized some of his associates genuinely in the last meters of the dash in Vittel.
“We will apply article 12.104 of the principles of the UCI… in which case commissaires (the race jury) can choose to implement a judgment to exclude a rider.”
Cavendish was unfortunate to fall off the most exceedingly terrible. I likewise think Sagan has fallen off unfortunate. It is to a great degree cruel.
He was in a position he couldn’t get himself out of. The bicycle was originating from underneath him and the elbow coming up is a characteristic sense of the rider. He was cockeyed too.
It is valid from first look it gives the idea that he gets his elbow up and ‘whack, have some of that, Cavendish’. It aggravated it look than it was.
At first we heard that they had consigned Sagan to the back of the peloton and a 30-second punishment. I believed that was reasonable. Something must be done and they expected to settle on a choice.
After a hour they precluded him. It is terrible for Sagan and truly awful for the race – the best on the planet with a potential green pullover going home. It is an overcome choice by the commissaires.
They have said it is a sporadic run. That is run; they are all sporadic.
Had Sagan not done what he did he would have gone down himself. He had no place to go other than to put his brakes on and they don’t do that.
The 207km phase from Mondorf-les-Bains had been a moderately calm race after Belgian Guillaume van Keirsbulck made a performance break from the begin.
He drove for around 191km, building a lead of 13 minutes, before being gotten by the peloton as the groups of the sprinters bumped to get their riders in the best positions.
Welshman Thomas was additionally gotten down a different crash in the end arranges however stated: “Fortunately I took off the greater part of the speed.”
He said Team Sky partner Froome was likewise “alright” in the wake of being held up by the occurrence.
Thomas went too far over two minutes after Demare, but since the crash occurred in the last 3km on an assigned run organize, he was credited with an indistinguishable time from the victor and holds the yellow pullover.
Alexander Kristoff was elevated to second and Andre Greipel third after the preclusion of Sagan, who completed second.
The various general arrangement riders completed with a similar time, which means no huge changes in the standings.
Stage five is the principal peak complete of the race, at La Planche des Belles Filles, the scene of Froome’s first Tour arrange win in 2012.
