Walker has been ruled out for the remainder of the season so he can work out in preparation for the 2022-23 campaign, Adrian Wojnarowski of ESPN reports.
Walker dealt with a knee injury earlier in the season but appeared in 13 of the Knicks' 15 games ahead of the All-Star break. He has one year remaining on his contract following the 2021-22 campaign, and his shutdown will allow for Walker and the Knicks to explore potential trades during the offseason. Derrick Rose (ankle) is expected to return to the Knicks' lineup Feb. 25 and should serve as the team's primary point guard, while Immanuel Quickley, Alec Burks and Ryan Arcidiacono should also see additional work in the backcourt. After signing with the Knicks in August, Walker made 37 appearances and averaged 11.6 points, 3.5 assists and 3.0 rebounds in 25.6 minutes per game.
