Manager Pete Mackanin acknowledged Wednesday that Nola (elbow) could miss the rest of the season, Todd Zolecki of MLB.com reports.

The Phillies scratched Nola from his scheduled start Wednesday and subsequently placed the 23-year-old on the DL with a right elbow strain. While Nola hopes his season isn't finished, Mackanin offered a sobering but perhaps more realistic take on the matter, suggesting Nola may just remain shut down for the remainder of the year with mid-September looking like a best-case scenario for his return. The right-hander had struggled mightily since the start of June but the team was adamant that there was nothing wrong with him, physically. Regardless, Phil Klein is starting in place of Nola on Wednesday, and prospect Jake Thompson will be an option to join the rotation the next time through.
