Troy Tulowitzki, Jorge De La Rosa exit Rockies' game vs. Giants with injuriers

The Rockies suffered a couple of potentially huge blows on Friday with injuries to star shortstop Troy Tulowitzki and starting pitcher Jorge De La Rosa.

De La Rosa went down first, tweaking his back in the third inning. He was visited by the training and coaching staffs but was allowed to finish the inning, surrendering a couple of runs before being removed prior to the bottom of the fourth in favor of Tommy Kahnle. Five and a half innings later, Tulowitzki suffered an apparent foot injury on a ninth-inning leadoff single that broke a streak of 16 consecutive batters retired by Giants pitching.

The Rockies rallied for five runs in the inning.

De La Rosa's injury -- lower back tightness, according to Rockies PR -- has him listed as day-to-day. If he's unable to make his next start, the Rockies have a couple of options. One is Franklin Morales, who is pitching well out of the bullpen but keeps having to return to the rotation due to injuries. Another might be Tyler Anderson, who tossed 5.2 scoreless innings for Tulsa tonight and would be right on schedule to make a start in place of JDLR.

There has been no official announcement on Tulowitzki's injury, but we'll be sure to keep you posted.

UPDATE (12:06 a.m. MT): Tulowitzki sprained a toe on his right foot, according to Nick Groke of the Denver Post. After the game, he had an X-ray, the result of which was negative, adds MLB.com's Thomas Harding.
