Canisius College announced the addition of three players and the departure of three others from its men’s basketball program.

Coach Jim Baron said Kassius Robertson of Toronto and Jeremiah Williams from Grand Rapids, Mich., signed letter of intents to join the program for the upcoming season. Baron also announced Chris Perez, who spent the past three seasons and graduated from Stetson, has received a waiver from the NCAA that will allow him to play this season while he works toward his master’s degree.

“We are excited to add these three players to our 2013-14 roster,” Baron said. “We have some big holes to try and fill, especially with losing two starters and offensive pieces ... to graduation.”

Besides losing Isaac Sosa and Harold Washington to graduation, junior Reggie Groves, who has already earned his bachelor’s degree, has chosen to transfer to North Carolina Central.

Baron also said sophomore Tyrel Edwards and freshman Jermaine Johnson have been granted their release from the school so that they can transfer elsewhere.
