Forward Thanasis Antetokounmpo has agreed to a two-year, minimum contract to join the Milwaukee Bucks, a source confirmed to ESPN.

The news was first reported by Eurohoops.net.

Antetokounmpo, the older brother of Bucks star and NBA MVP Giannis Antetokounmpo, averaged 3.6 points and 2.2 rebounds in 33 games, including 26 starts, last season with Panathinaikos B.C. of the EuroLeague. He was initially drafted by the New York Knicks in the second round of the 2014 NBA draft.

The 6-foot-7-foot Antetokounmpo played with New York's G League club, the Westchester Knicks, for two seasons, averaging 10 points, 4.3 rebounds and 1.7 assists per game in his final season. He shot 55 percent from the floor and 28 percent from beyond the 3-point arc.

He appeared in three preseason games with the Knicks, recording four rebounds and two assists over 13 minutes. The Knicks brought him back on a 10-day contract after releasing him before the 2015-16 season started.
