Cubs manager Craig Counsell said after Sunday's 2-1 extra-inning loss to the Giants that Taillon (hamstring) will be headed to the 15-day injured list, Marquee Sports Network reports. Taillon was charged with an earned run on two hits and two walks while striking out two batters over one inning before he was forced out of his start Sunday in the top of the second due to a left hamstring strain. Counsell noted that the severity of the injury until Taillon receives imaging Monday, but the Cubs have already determined that the hamstring strain will keep the right-hander out of commission for at least the next two weeks. Javier Assad tossed 6.1 shutout innings in long relief following Taillon's departure Sunday, but Assad could end up sticking in the bullpen if Matthew Boyd (knee) is cleared to return from the 15-day IL by the time Taillon's turn in the rotation comes up next weekend in San Francisco.

Dealing with hamstring injury
Taillon suffered a left hamstring strain in the second inning of Sunday night's contest against the Giants, Bruce Levine of 670TheScore.com reports. Taillon pulled up lame on the final pitch of a six-pitch walk to Matt Chapman in the top of the second inning, and his departure is now understood to be the result of a hamstring injury. The right-hander may now be placed on the 15-day injured list, and depending on the severity of the strain, Taillon could be forced to miss extended time. Javier Assad, who replaced Taillon on Sunday, is the most likely candidate to replace him in the rotation moving forward if a trip to the IL is required.
Exits early Sunday
Taillon (undisclosed) left Sunday's start against the Giants in the second inning, Jesse Rogers of ESPN.com reports. Taillon surrendered one run on two hits and a walk in the top of the first inning before walking Matt Chapman to open the top of the second. The right-hander immediately signaled to the Cubs' dugout after his final pitch to Chapman, and he was promptly removed from the contest. It's unclear what exactly caused Taillon's early departure, but more information on his status will likely be provided in the near future. In the meantime, Javier Assad replaced him on the mound against San Francisco.
