The New York Knicks have waived power forward Taj Gibson and declined their contact option on forward Bobby Portis Jr., but may have interest in bringing back both players, per Ian Begley of SNY.tv.

The Knicks also parted ways with guards Elfrid Payton and Wayne Elligton. The roster purge resulted in $40 million in cap space under the new team president Leon Rose. Knicks salary-cap expert Brock Aller is also new, after spending nearly two decades with the Cleveland Cavaliers.

When it comes to Gibson, the Phoenix Suns, Golden State Warriors and Los Angeles Clippers are among the others to watch, per Darren Wolfson of 5 Eyewitness News.

Both Gibson and Portis will be unrestricted free agents once it begins Friday (6 p.m. EST).
