2018 NBA Draft Rumors: Grizzlies 'Seriously Considering' Michael Porter Jr.

Michael Porter Jr. is a bit of a mystery as an NBA draft prospect after having missed almost all of his only college season with a back injury. At least two teams at the top of the draft, however, reportedly have him on their short lists.

According to Sam Amick of USA Today, the Memphis Grizzlies are "seriously considering" selecting Porter with the No. 4 overall pick.

Amick previously reported the Sacramento Kings have "a very real chance" of taking Porter at No. 2 but added Saturday that both teams could trade down.

Porter, who played just three games at Missouri for a total of 53 minutes, was set to work out Friday in front of NBA teams, but it was canceled because of a hip injury, according to Jonathan Givony of ESPN.com.

He still took part in an invitation-only medical examination for teams in Chicago.

Sean Cunningham of ABC10 in Sacramento reported the evaluation went well for the prospect.

According to Shams Charania of Yahoo Sports, an MRI also returned with a "positive review" Thursday after he suffered hip spasms.

While the unknown could cause teams to pass on Porter, Givony reported Porter is unlikely to fall out of the top seven. The Chicago Bulls have the No. 7 pick and have been linked to the forward in the past.

Bleacher Report's Jonathan Wasserman had the 6'10" Porter going to Chicago in his latest mock draft.
