With the ​NBA Draft exactly one week away, players and NBA teams alike share the same worst nightmare: injury.

For ​Michael Porter Jr., whose injuries have plagued him during his brief college career and the NBA Combine, his worst nightmare just occurred. Porter Jr. had to cancel his Pro Day workout in Chicago because of a hip strain that was causing him to have hip spasms.

This is horrible news for Porter Jr., who could have used the last-minute NBA looks from teams like the Knicks, Suns, and Kings (No. 2 pick in Draft). ​

Porter Jr.'s journey through the NBA Draft process has been very interesting. At one point, he was ranked the No. 1 prospect coming out of high school. For much of the 2017 season, he was projected to be a top two pick in the draft. Currently, he is expected to go in the top seven. 

Injuries have been the name of the game so far. His freshman season at Missouri was disrupted by back surgery, and he was only cleared to play two weeks prior to his first Pro Day. Now, a hip injury has derailed another Pro Day.

At this point, there are many teams interested in Porter Jr., like the Grizzlies (No. 4 pick) and the Mavericks (No. 5), along with the teams planning on attending the workout in Chicago. But every team at this point has to be concerned about his history with injuries.
