Portland Trail Blazers forward Zach Collins has been diagnosed with a stress reaction injury in his left ankle and will be reevaluated in a week, the team said after an MRI.

That rules Collins out for Thursday's Game 2 of the team's first-round playoff series against the Los Angeles Lakers, Game 3 on Saturday and Game 4 on Monday.

Collins left the Blazers' play-in game against Memphis on Saturday with the injury and missed Tuesday's Game 1 win.

A first-round pick out of Gonzaga in 2017, Collins averaged 7.0 points and 6.3 rebounds this season for the Trail Blazers.
