Rockies starting pitcher Jordan Lyles will undergo surgery on his injured toe and will miss the rest of the 2015, according to Dargan Southard of MLB.com:

Lyles made 10 starts this seasons, posting a 5.14 ERA and 1.49 WHIP. He walked 19 and struck out 30. In two seasons with the Rockies, Lyles has a 4.56 ERA and 1.40 WHIP to go with a 4.09 FIP in 175⅔ innings. He missed time last season with a broken hand that was the result of a play at the plate.
Lyles went seven days between starts after being hit in the toe with a line drive against the Giants. He then landed on the toe awkwardly in the second inning against the Phillies Sunday and left the game.
The two most likely options to replace Lyles are David Hale, who has started two nightcaps of doubleheaders this season as the 26th man on the Rockies roster, and Chris Rusin, who made a spot start against the Reds last week and threw 4⅔ innings in relief of Lyles on Sunday. Hale and Rusin have combined for a 2.59 ERA in 24⅓ innings this season, allowing 23 hits and five walks while striking out 14.
The Rockies could, however, take a third option and call up top prospect Jon Gray, who had a very strong May at Triple-A Albuquerque, posting a 2.78 ERA and 1.18 WHIP over 35⅔ innings, giving up 33 hits and walking nine while striking out 21. Gray pitched seven shutout innings in his most recent start on Sunday, allowing four hits and two walks, striking out six.
Whoever fills in for Lyles will likely start Saturday against the Miami Marlins at Coors Field.
