The "general feeling" is that Marlins pitcher Henderson Alvarez is not dealing with a serious injury to his shoulder, MLB.com reports.

Alvarez could be back in as little as 15 days and may not be sidelined more than a month with the shoulder issue. He was placed on the disabled list Monday after an MRI revealed inflammation in his shoulder. Alvarez is 0-2 with a 4.50 ERA and 5:1 K:BB ratio in 12 innings over his first two starts.
