Porter will start Thursday's matchup against the Grizzlies, Anthony Slater of The Athletic reports.
With Andrew Wiggins (COVID-19 protocols) out, Jonathan Kuminga has started at small forward for the Warriors in each of the last two games. However, Kuminga picked up a back injury during Monday's win over the Kings. The rookie will be active for Thursday's contest, but Steve Kerr has elected to roll with the veteran Porter in his starting lineup.
