Joshua Ho-Sang, one of the Islanders' most promising prospects, was late for the first day of the team's training camp Friday morning and was subsequently returned to Niagara of the Ontario League, ending the 19-year-old's training camp before it even began.

Ho-Sang was the 28th pick of the 2014 NHL Draft, a player considered to have top-10 talent who slipped late to the first round because of supposed issues with his attitude. He had a strong season in the OHL, especially after a trade to Niagara. The young forward had 14 goals and 48 assists in 49 games with the IceDogs.

Ho-Sang attended the Isles' prospect camp in July and had been at the extended prospect camp which began a week ago, working alongside fellow elite prospects Michael Dal Colle, Mathew Barzal and Ryan Pulock. Sources said Ho-Sang's behavior throughout his time on the Island this summer had been exemplary.

Jack Capuano had Ho-Sang working on a training-camp line with John Tavares and Anders Lee. But Ho-Sang's no-show Friday morning left only Lee and Tavares wearing white jerseys during drills, as general manager Garth Snow sent a message that no player, especially a 19-year-old, can break team rules without a severe punishment.
