Sexton did not return to Wednesday's 123-112 win over the Bucks and required stitches to close a cut on his forehead, Thuc Nhi Nguyen of the Los Angeles Times reports.
Sexton knocked noggins with Ryan Rollins, but it sounds like he's avoided a concussion, so he should be able to get out there for Sunday's game in Phoenix. Austin Reaves (heel) also exited Wednesday's game, and if he needs to sit out Sunday, Sexton would have the chance for some extended minutes.
