How Bad Is The Conley Injury?

Mike Conley left game 5 of the Grizzlies series early with hamstring soreness. He is currently listed as day to day which means it's probably a bigger deal than just resting him due to his past injury. Conley was a huge part of the round one win for the Jazz so what should we expect from Conley in the second round. When will he return and what's the outlook for the Jazz if Conley does miss a significant amount of time?
