After playing through an injury to his labrum during the 2015 and 2016 seasons, Luck underwent surgery last January with the hope he would enter the 2017 campaign at full strength. That never came to fruition, however, as Luck made limited progress in his recovery in the months that followed before being shuttered for good in November when his shoulder responded poorly to light throwing. Following his shutdown, Luck headed to Europe for additional treatment, with the Colts announcing shortly thereafter that a follow-up surgery wouldn't be necessary for the franchise signal caller. While Chris Mortensen of ESPN reported Sunday that doctors who have examined Luck still have concerns about his shoulder, Ballard's comments suggest that at least within the organization, there isn't as much worry regarding Luck's health outlook for 2018. Regardless, Luck will need to get back on the field and throw without discomfort at some point during the offseason before there can be any optimism that his lingering shoulder woes are firmly in the rear-view mirror.
