Even when you're a pro cyclist, it's a good idea to wear a helmet.
Cyclist Jesse Sergent was forced to drop out of the Tour of Flanders on Sunday after being clipped by a service car during the race. The car usually assists cyclists during the race but this time it did the opposite when it tried to avoid a curb and instead hit the 26-year-old and sent him falling to the ground.
Unfortunately 'no harm, no foul' doesn't apply here. According to Cycling News, Sergent left the race with a broken collarbone.
Other cyclists tweeted their disappointment about the incident.
Months of hard work and sacrifice to be knocked off by a neutral service car! This is not acceptable! Really feel for @jessesergent
Hopefully Sergent's recovery goes smoothly and we see him back on the roads soon.
