Young struck out on a checked swing against Josh Johnson, and although there was nothing visibly wrong as he walked back to the dugout, he did not return to left field for the top of the second. Andrew Brown, who was called up Sunday to replace the injured Michael Cuddyer on the roster, took Young's place in left.
A subsequent report from the dugout was that Young was removed from the game with a left intercostal muscle strain, an injury to the rib cage.
Young has had a hot August and played himself into a fixture atop the Rockies lineup card. He had a seven-game hitting streak come to an end Saturday night, having hit .469 (15-for-32) with a pair of homers during the stretch, and his 29 hits since July 31 are the most in the National League. He has scored 16 runs and logged 11 multi-hit games in that 15-start span.
A few innings later, Josh Rutledge was removed from the game for pinch-hitter DJ LeMahieu with two out and one on in the fifth. The report from the dugout was the Rutledge was removed with left quad tightness. He has been dealing with the ailment over the past week.
Rutledge, who entered the game hitting .328 with six homers and 22 RBIs since his July 13 call-up, beat out an infield single in the fourth inning and collided with Brown's glove in left after running down a fly ball, knocking the ball out of Brown's grasp for a two-base error.
Le Mahieu took second in the field with Jonathan Herrera moving from second to short.
