The Phoenix Suns have brought in free-agent shooting guards R.J. Hunter, Andre Dawkins, Isaiah Canaan, and Xavier Silas for workouts, Scott Bordow of AZcentral reports.

One or two of the four could be invited to training camp and fight for a place in the Suns' backcourt, which has lost guards Brandon Knight and rookie second-round pick Davon Reed to long-term knee injuries this offseason. Elijah Millsap is currently slated as the lone backup for starting shooting guard Devin Booker.

Canaan is the most experienced of the four, having spent five seasons in the NBA. He averaged 4.6 points in 39 games last season for the Chicago Bulls. However, he’s only six-feet tall and will be a major defensive liability if played at shooting guard.

Hunter, meanwhile, is the lone first-round pick in the group after he was drafted No. 28 overall by the Boston Celtics in 2015. He had a reputation as a big-time scorer and shooter in college, but has not managed to establish himself in the league.

Andre Dawkins and Xavier Silas are both undrafted guards who have bounced around in the G-League as well as overseas. The 25-year-old Dawkins has played just four games in the NBA after coming out of Duke in 2014, while the 29-year-old Silas last played an NBA game in 2012.
