The Sixers signed power forward James Michael McAdoo to a two-way contract and agreed to terms with guard James Blackmon Jr., team president Bryan Colangelo announced Wednesday.

McAdoo, a 6-foot-9, 230-pounder who played in college at North Carolina, went undrafted in 2014 and played with the Golden State Warriors the last three seasons, seeing action in a total of 108 games. He can boast both G-League and NBA championships, having averaged 3 points and 1.7 rebounds in 7.9 minutes with Golden State.

NBA teams can sign two players to two-way contracts in addition to their 15-man regular-season roster. Those players will play with the team's G-League affiliate but can spend up to 45 days with the NBA squad, not including time spent before the start of development league training camp or time after the G-League regular season.

McAdoo is the first player the Sixers have signed to a two-way deal with the Delaware 87ers. Although two-way players can spend up to 45 days with the NBA team, no time is guaranteed.

Hall of Famer Bob McAdoo, who finished a 14-year NBA career with the Sixers in 1986, is the second cousin of McAdoo's father.

Blackmon played for the Sixers' summer teams in Utah and Las Vegas this year along with attending the team's rookie minicamp. He appeared in a total of five games, including one start, and averaged eight points in 16 minutes.

The 6-4 Blackmon went undrafted after playing three seasons at Indiana, where he averaged 17 points, 4.8 rebounds, and 1.9 assists as a junior last season.
