Grimes will start in Sunday's game against the Pistons.
With Luka Doncic (back) sidelined for this contest, Grimes will enter the starting lineup for the second time this season. Grimes' only start came in the 103-87 win over the Clippers on Oct. 28, with the former 76er finishing with 23 points, three rebounds, five assists and four steals across 38 minutes.
