The Knicks have added to their frontcourt in NBA free agency. Guerschon Yabusele is signing a two-year, $12 million contract with the team, with The Post’s Stefan Bondy reporting the deal includes a player option. The 29-year-old averaged 11 points and 5.6 rebounds in 70 games for the 76ers this season.

Guerschon Yabusele has parted ways with the Philadelphia 76ers, and his new destination probably stings for fans much more than they initially expected. Leading

For the Knicks he likely will take the place of free agent Precious Achiuwa. At 6-8, 260-pounds, the 29-year-old Yabusele can serve as both a power forward and center as Achiuwa did last season. But Yabusele is a more dangerous threat from beyond the arc than Achiuwa, who has shot under 30% beyond the arc for three straight seasons.
