The Portland Trail Blazers announced Tuesday that big man Zach Collins will miss at least four months after undergoing shoulder surgery.

Collins underwent successful surgery to repair his left labrum. He will begin a treatment and rehabilitation process and be re-evaluated in approximately four months.

In the first three games of the season, Collins averaged 9.0 points, 4.0 rebounds and 2.0 assists while shooting 47.4 percent from the field, 42.9 percent from beyond the arc and a perfect 100 percent from the free-throw line.

For his career, Collins holds averages of 5.7 points, 3.8 rebounds and 0.9 assists in 146 games. He is making $4,240,200 this season. The Blazers will miss his energy, toughness and rebounding, especially on the defensive side of the floor.

It has been a slow start for Portland. The Blazers suffered a bad loss on Monday, losing to a Golden State Warriors team playing without All-Stars Stephen Curry, Draymond Green and D'Angelo Russell. Before losing to the Warriors, the Blazers blew a big lead to the Philadelphia 76ers at home and wound up losing on a Furkan Korkmaz game-winning 3-pointer in the final second.

Portland is 3-4 on the season. The Blazers will look to get back in the win column against Kawhi Leonard and the Los Angeles Clippers on Thursday.
