DENVER -- The September reinforcements from the Minor League ranks come at a good time for the Rockies, who are dealing with a host of injuries.
Outfielder Ryan Spilborghs, who came off the disabled list on Friday, re-injured his ailing right foot while making a play in left field during Colorado's 10-7 loss to the D-backs on Monday.
"It's significant enough to the point where I don't think you're going to see him again this year," Rockies manager Jim Tracy said.
Second baseman Jonathan Herrera will also miss the rest of the season. He fractured the index and pinky fingers on his right hand after the hand was slammed in a door on Sunday night. Tracy said Herrera's injuries will not require surgery.
"We dodged a bullet," Tracy said.
Herrera's mishap marked the second time that a Rockies player fractured a finger in a door this season. Right-hander Aaron Cook missed the first eight weeks of the season after he slammed his right ring finger in a door during Spring Training.
In other injury news, first baseman Todd Helton was out of the lineup for the third straight game on Tuesday, as he continues to rest a stiff back. Tracy said that the earliest Helton will play is Friday's series opener against the Reds.
Infielder Chris Nelson -- who joined the Rockies from Triple-A Colorado Springs on Tuesday but is yet to be activated -- is nursing a bruised left heel. Nelson was in a protective boot on Tuesday, but he could make another appearance with the Rockies before the season ends.
Also, Rockies catcher Jose Morales, who was placed on the 60-day disabled list on June 17 after suffering a fractured right thumb, said on Tuesday that he will miss the rest of the season.
The switch-hitting Morales, who underwent surgery on his right wrist after the 2009 season, began experiencing similar pain in his left wrist while trying to come back. He said rather than taking an anti-inflammatory shot in an attempt to make it back for limited playing time, he will rest, play winter ball in Puerto Rico and hope to be ready next season.
