Smith, 35, is 6-foot-0 and has played for 13 teams during his 14-year NBA career — including a previous stop with the Hornets in 2021-22.
He spent last season with the eventual champion Nuggets, appearing in 43 games before entering free agency this summer. Smith appeared in 65 games total in 2021-22, averaging 6.3 points and 3.8 assists.
Sumner, 27, is 6-4 and was on track to be one of just four players across the NBA to make an opening night roster despite entering training camp on a non-guaranteed deal. It appears that will no longer be the case.
He appeared in 53 games with the Nets last season, averaging 7.1 points and shooting 46 percent from the field, including 36 percent on 3-pointers.
