The Miami Heat are making a late-season push for the last playoff spot in the Eastern Conference. But on Thursday night, the team received some bad news about one of their most recent additions – Jarrett Jack.

Via Ira Winderman of the South Florida Sun Sentinel:

Jack, 35, was claimed earlier this month by Miami's G League team. He played only one game for the Sioux Falls Skyforce before injuring himself in Saturday's contest. The injuries to his left ACL, lateral meniscus and MCL will cost him the rest of the year.

The point guard has put together a 13-season NBA career. Jack has spent time with the Portland Trail Blazers, Indianapolis Pacers, Toronto Raptors, New Orleans Hornets, Golden State Warriors, Cleveland Cavaliers, Brooklyn Nets, New Orleans Pelicans and New York Knicks.

Last season, he was the Knicks' regular starter at point guard. He averaged just 7.5 points, 3.1 rebounds and 5.6 assists while shooting 42.7%. Over his career, Jack has posted 10.8 points, 2.9 rebounds and 4.6 assists while shooting 44.0%.

Unfortunately, given his age and decline, this injury could mean the end of Jack's NBA career. If so, he can take solace in his long career as a solid and well-respected player.

Jack was unlikely to make the Heat, as they are deep at point guard. Young starter Justise Winslow is having a career year while back-up Goran Dragic has been great off the bench. The team is 32-35 and holds the eighth seed in the Eastern Conference. ESPN's BPI Playoff Odds give the team a 49.7% chance of making the postseason.
