The Chicago Cubs have placed right-hander Carl Edwards Jr. on the 10-day IL with an upper back issue. Before the injury, Edwards was back with the Cubs for the third time this season after multiple stints in their minor league system.


Edwards' roster spot will be taken by lefty Tim Collins, who's being called up from the Cubs' Triple-A affiliate. He has appeared in five MLB games this season so far.


Edwards reported the injury on June 10, just a day after he pitched recorded two outs in a 5-1 win over the Cardinals.


The 27-year-old relief pitcher had a rough start to the season, earning himself time in in the minors. He was recalled back to the Cubs in early May and has produced solid results since then, posting a 2.03 ERA through 13.1 innings following his return.


With opposing hitters only hitting .094 against him through those 13.1 innings, it looked as though Edwards was trending in the right direction. Depending on the severity of the injury and Edwards' recovery, he'll miss series against the Dodgers and White Sox along with the majority of a four-game series with the Mets.
