Johann Muller says he has yet to decide on his Ulster future

Veteran Johann Muller says he will make a decision on his Ulster future within the next four or five weeks.

Muller, 34, has been troubled by injury over the past two seasons and the South African World Cup winner says he will "listen to my body" before making his decision.

The lock is hoping to be passed fit to line out for Ulster in Friday's Heineken Cup game against out-of-contention Montpellier.
