No timetable for QB Luck’s return

Andrew Luck isn’t sure when he’ll start throwing again and won’t set a timetable for his return from shoulder surgery. The Indianapolis Colts’ starting quarterback isn’t expected to do much — if any work — during the team’s off-season workouts. Players and coaches held their first official team activities Monday at the team complex, and for the first time Luck acknowledged his injury problems began during a Week 3 contest at Tennessee in 2015. He missed nine games that season with an assortment of injuries, including a lacerated kidney. After the season, Luck said he opted for rehab rather than surgery. But after aggravating the injury several times last season, he decided to have surgery.
