Rodney McGruder underwent successful surgery to repair a left tibia stress fracture. The 90-minute procedure was performed by Dr. Charles Jordan and Heat team physician Dr. Harlan Selesnick at Miami Orthopedics & Sports Medicine Institute at Doctors Hospital.

He is expected to begin rehabilitation in one week. A timetable for his return has not been set.

McGruder appeared in five preseason games (five starts) with the Heat, averaging 7.2 points, 2.8 rebounds, 1.6 assists and 22.3 minutes while shooting 51.9 percent from the field and 44.4 percent from three-point range.

The Miami Heat have converted the contract of Matt Williams Jr. into a two-way contract.

Williams Jr., who was originally signed by the Heat on July 24, appeared in all six preseason games with Miami and averaged 2.2 points in 6.4 minutes of action. He scored nine points on 3-of-6 shooting from three-point range in a win vs. Washington on October 11. Williams Jr. previously appeared in eight Summer League games (six starts) with the HEAT in Orlando and Las Vegas and averaged 9.9 points and 2.6 rebounds while shooting 38 percent from the field, 39 percent from three-point range and a perfect 2-of-2 from the foul line. He started all six games in Las Vegas with Miami and shot 45 percent from three-point range, leading the team in three-point field goals made four times, including a 5-of-8 performance from beyond the arc vs. Washington on July 10 and a 6-of-9 output from downtown vs. Memphis on July 15.

The University of Central Florida graduate finished his collegiate career as the school’s all-time leader in three-point field goals made (274) and became the 18th player in program history to score at least 1,000 points.

Rodney McGruder will miss three to six months with a stress fracture in his left leg.

McGruder will likely undergo surgery.

McGruder was expected to start for the Miami Heat for the second straight season.

Coming out of Kansas State in 2013, McGruder went undrafted before eventually emerging with the Heat.

The Miami Heat have signed forward Tony Mitchell and waived guard Larry Drew II. 

Mitchell has appeared in 78 NBA G League games (52 starts) and averaged 21.2 points, 5.9 points, 2.8 assists, 1.28 steals and 32.7 minutes while shooting 42.5 percent from the field. He earned G League Rookie of the Year honors in 2013 while being named to the All-G League First Team and All-G League Rookie Team. The 2013 All-Star also captured back-to-back Slam Dunk titles in 2013 and 2014. Mitchell has spent the last three seasons overseas playing for a variety of teams, most recently he split last season between three teams, appearing in 35 games (13 starts) averaging 13.0 points, 3.7 rebounds, 1.6 assists and 21.6 minutes while shooting 42 percent from the field.

Mitchell has appeared in three career NBA games, all with the Milwaukee Bucks during the 2013-14 season, totaling six points, one rebound, one assist and a steal while shooting 60 percent (3-of-5) from the field.

Drew II, who was signed by the Heat on September 5, appeared in one preseason game totaling one rebound, one assist and a steal in 5:00 minutes of action on October 5 at Brooklyn.

The Miami Heat have signed DeAndre Liggins. 

Liggins, who was originally signed by the Heat to two 10-day contracts in 2014, spent two seasons with Miami’s NBA G League affiliate, the Sioux Falls Skyforce, helping them capture the 2016 Championship after appearing in 34 games (33 starts) and averaging 13.0 points, 7.0 assists, 6.3 rebounds, 2.06 steals and 38.4 minutes while shooting 42.8 percent from the field, 43.4 percent from three-point range and 71.1 percent from the foul line. 

Liggins split last season between the Dallas Mavericks and Cleveland Cavaliers appearing in 62 games (19 starts) and averaged 2.5 points and 1.7 rebounds in 12.5 minutes of action. He has appeared in 119 career NBA games (20 starts) averaging 2.1 points, 1.5 rebounds and 9.9 minutes while shooting 41.4 percent from the field.

The Miami Heat are interested in experimenting with playing Hassan Whiteside and Kelly Olynyk together during the preseason.

Olynyk signed a four-year, $50 million contract with the Heat in the offseason.

“They will have the ability to play together,” Erik Spoelstra said. “How much will depend. Their games are so different. Their skill sets complement each other.”

Whiteside is intrigued by the combination, saying Olynyk is “a really good passer. He can space the floor. He's physical. So it's going to be good.”
