The Chicago Cubs got some good news on the injury front Thursday regarding pitchers John Lackey and Hector Rondon, but another pitcher had an unfortunate setback in his recovery.

That pitcher is reliever Pedro Strop, who is working his way back from a torn meniscus in his left knee. During his rehab, Strop suffered a strained right groin, and the setback has added at least two weeks onto his timetable to return, according to the Cubs.

With the setback, it appears that Strop will still come back before the end of the season, but his return would come more on the back end of his original four-to-six week timetable, instead of the beginning of that window that team doctors were hoping he would return in.

Even with that setback, all is not bleak on the North Side, as the Cubs got good news about two of their key contributors on Thursday. Before the team’s game against the San Francisco Giants, Lackey threw a side session at Wrigley Field, and he told reporters that everything went well. He is likely going to start for the Cubs Sunday when they wrap up their four-game series with the Giants.

As for Rondon, his return is close, but won’t occur during the team’s current homestand. According to the Cubs, the pitcher will go out on a rehab assignment to triple-A Iowa, with the plan being to have him pitch on Saturday and on Monday with the team. If all goes well, he should be back in the Cubs’ bullpen toward the middle of next week when the team is on a road trip to Milwaukee and Houston. 

The Cubs will need their bullpen to get back to full strength soon, as they have just 30 games remaining in the regular season. Players like Aroldis Chapman, Carl Edwards Jr, and Rob Zastryzny have shouldered the load, but others like Travis Wood have struggled as roles have been shuffled thanks to the injuries.
