Joe Nathan appeared to re-injure his right elbow after throwing just 10 pitches during a Minor League game Wednesday morning.

Nathan, 40, had targeted Friday as his return to the Detroit Tigers from the disabled list with an elbow strain.

The right-hander was scheduled to throw 25 pitches for Triple-A Toledo as he entered the game in the seventh inning. Nathan reportedly clutched his elbow and was checked by trainers after a strike to his third batter and immediately went to the clubhouse after just one warm-up throw.
