Luck’s shoulder still has healing to do

Indianapolis Colts quarterback Andrew Luck said Monday he’s still not sure when he’ll be able to start throwing passes again.

Three months after having surgery on his right shoulder, Luck showed up for opening day of the Colts’ offseason workouts without the sling he had been wearing to protect his throwing arm.

‘‘ I am where the physical therapists, trainers and doctors say I am; I’m not going to worry about it,’’ said Luck, who declined to provide a timetable for his return. ‘‘ I have full trust in the guys helping me out. I want to play, but I’m not going to worry about it.’’

Colts officials already have said they don’t expect Luck to participate in many — if any — on- field drills between now and the end of June. The hope is that Luck, who has been plagued by injuries the last two seasons, will be healthy enough to return to action for the start of training camp in July.

McDonald charge tossed

A judge in Santa Clara County, California, dismissed a rape charge against former Bears and San Francisco 49ers defensive end Ray McDonald after prosecutors said the woman who made the allegation refused to testify.

Judge David A. Cena dismissed the charge — one count of rape of an intoxicated person — stemming from an incident in December 2014 at McDonald’s home in San Jose, California. Santa Clara County prosecutor Chris Lamiero said in a statement that he tried to convince the victim to testify, but she refused.

The Bears signedMcDonald to a one- year contract in March 2015 and released him two months later after he was arrested on charges of domestic violence and child endangerment.
