Grimes (knee) said Tuesday that he is "definitely 100 percent" ahead of Dallas' training camp, Grant Afseth of SI.com reports.
Due to a right knee sprain he suffered in January, Grimes played in only six games with Detroit after the Pistons acquired him via trade Feb. 8. The 24-year-old was a part of another deal this offseason, as he was sent to Mavericks in exchange for Tim Hardaway. Grimes appeared in 51 regular-season games last season with the Knicks and Pistons, averaging 7.0 points, 2.0 rebounds and 1.3 assists across 20.1 minutes.
