The IOC has voted to drop wrestling from the list of core Olympic Games sports, a necessary step to make room for more relevant sports for today. Wrestling still has a chance to be on the program, though it will now join the seven shortlisted sports which are aiming for inclusion in the 2020 Olympic program: baseball/softball, karate, roller sports, sport climbing, squash, wakeboarding and wushu.
You can vote for which sport you think should be included in the Olympics. It is very unlikely that wrestling will be added back on the program, maybe something cool like climbing should be added. Dropping wrestling was a surprise to me, as it seemed like modern pentathlon was on the chopping block. There are a few other sports that should possibly be eliminated.
The word from an IOC inside source indicated that wrestling was voted out from a final group that also included modern pentathlon, taekwondo and field hockey, which gives an idea of which sports may next be on the chopping block. It seems like there is a bit more culling to do.
