Facing injuries, Heat call up Matt Williams Jr.

The Miami Heat announced Tuesday that they have called up guard Matt Williams Jr. from the Sioux Falls Skyforce, Miami’s affiliate team in the developmental league.

Williams and forward Derrick Walton Jr. are the Heat’s players on two-way contracts, which allow teams to sign players to 16th and 17th roster spots. Those players can play up to 45 days with their NBA teams, primarily residing with the G League team. Both players are currently with the team.

The Heat faced their toughest challenge yet last night, playing without Goran Dragic, James Johnson, Justise Winslow and Hassan Whiteside against the Atlanta Hawks. With such an injury-depleted roster — remember, Rodney McGruder and Okaro White are both out indefinitely — it makes sense that the Heat would use all the players they could use.

Williams provides depth in the backcourt, as Dragic may not play tomorrow night in Boston with a sore left elbow. Dion Waiters played through an illness Monday night, even having to vomit after the first quarter.
