Nieto suffered a fractured foot in the final few weeks of the regular season, CSN Bay Area's Kevin Kurz reports. While the injury didn't force Nieto to sit out any games at the time, it will prevent him from being available for the United States squad during the IIHF World Championships in May. The 22-year-old, who compiled 27 points over 72 games in 2014-15, should be ready to go when the Sharks reconvene for training camp in the fall.
