The New York Knicks are finalizing a two-year deal with forward Thanasis Antetokounmpo, a league source said.

The deal is expected to be completed as soon as Thursday and likely will have some guaranteed money but is not expected to be fully guaranteed.

The Knicks drafted Antetokounmpo, the older brother of Milwaukee Bucks star Giannis Antetokounmpo, late in the second round of the 2014 draft.

Somewhat surprisingly, Antetokounmpo decided to turn down a two-year, $550,000 deal overseas last summer to play for the Knicks' D-League team, which paid him $25,000.

Antetokounmpo's patience has now been rewarded with an NBA contract.

New York has 13 players under guaranteed contracts. Langston Galloway and Antetokounmpo are signed to partially guaranteed contracts. Galloway is expected to make the regular-season roster.

Antetokounmpo likely will battle with training-camp invitees Darion Atkins and Wesley Saunders -- and whomever else the Knicks invite to camp -- for the final roster spot.

Antetokounmpo, a 6-foot-6 wing with a 7-0 wingspan, has shown that he can defend well. But his jump shot lacks consistency at this point.

He shot 23 percent from beyond the arc last season for the Knicks' D-League team in Westchester. In the Las Vegas Summer League, Antetokounmpo hit just 28 percent of his 3-point attempts.

He'll need to improve those percentages in preseason if he wants to show the Knicks that he can be a 3-and-D wing.

Antetokounmpo's pending agreement was first reported by David Pick.
