Wellington Phoenix midfielder Carlos Hernandez will miss Sunday's away clash with the Melbourne Heart.
The Costa Rican international has been laboured in recent weeks with a calf tear and was due to go for an MRI scan this afternoon to further investigate the problem.
``What it's done is it's prevented him from training most of the week and then he's come in at the end of the week and it's beginning to tell on his work rate and fitness during a match,'' Phoenix coach Ernie Merrick said. ``So we have to get it right.''
With Hernandez out, Belgian import Stein Huysegems will likely drop in behind strikers Roy Krishna and Tyler Boyd, which makes for a dynamic attacking trio.
Utility Manny Muscat will return to the midfield this week after missing last Sunday's 1-1 draw with the Perth Glory due to suspension, while new recruit Shaun Timmins will start at left back in place of the injured Josh Brindell-South.
