Harris, who signed a partially guaranteed deal as an undrafted free agent after a solid run with L.A.'s summer league team, appeared in two games with the Lakers this season, registering one rebound, one assist and one steal in 11 minutes.
"I think he has a chance," Lakers coach Mike D'Antoni said of Harris. "I think he has a chance to be a good player -- not this year, it's going to take a little bit -- but if he continues to develop, he's somebody we should watch and hope the best for him. He was great and I think he's got a future in this league."
The Gonzaga University product was not with the Lakers on their three-game trip this week, staying in L.A. on assignment with the Los Angeles D-Fenders, the Lakers' D-League affiliate.
Harris appeared in one game for the D-Fenders and had 18 points, two rebounds and two assists before fouling out.
The Lakers' roster is now at 14 players.
