New York manager Joe Girardi made the announcement before playing Texas on Friday night. He said the Japanese right-hander will be limited to 65 pitches in his game for Scranton/Wilkes-Barre at Pawtucket, Rhode Island.
Girardi said it was possible that Tanaka could rejoin the Yankees after that minor league start.
Tanaka has been on the disabled list since April 27 because of tendinitis in his right wrist and a strained forearm. He pitched three scoreless innings Thursday in Triple-A, throwing 41 pitches.
Tanaka is 2-1 with a 3.22 ERA in four starts for the Yankees. He was an All-Star last year during his first season in the majors, but was slowed in the second half because of a tear in his elbow.
Girardi said Tanaka felt fine after his first rehab start.
