Johnson (illness) didn't play in Monday's 96-88 Summer League win over the Grizzlies but can be considered day-to-day moving forward, Ron Harrod Jr. of DLLS Sports reports.
Johnson is under the weather and was unable to suit up Monday after totaling 37 points, 13 rebounds, six blocks, five steals and three assists in Dallas' first two Las Vegas Summer League outings. His next chance to play will come against the Thunder on Thursday.
