Johann Muller still undecided whether to continue Ulster career

Johann Muller says he has yet to decide whether to prolong his Ulster career beyond this season.

The lock, 34, is mulling over a possible contract extension with the Ravenhill outfit or whether to end his career and return home to South Africa.

"I haven't made my decision yet about next year and the years to come. That will happen in the next four or five weeks," Muller told BBC Sport NI.

The Ulster captain's recent battles with injury may influence his decision.

Muller has been out of action for much of the current season because of a calf injury.

  • Represented South Africa at Under-19 level
  • Made Super Rugby debut for the Sharks in 2002

The South African World Cup winner, who moved to Ulster from Natal Sharks in 2010, was also ruled out for several weeks during last season because of arm and hand injuries.

Muller is hoping to be passed fit to play in Ulster's Heineken Cup game against Montpellier on Friday.

Despite Montpellier being out of contention for a place in the knockout stages, Muller is expecting a tough assignment at Ravenhill.

He was impressed with Montpellier's displays in both their defeats by Leicester when the Tigers edged 41-32 and 15-14 victories.

"They have been unlucky in the Heineken Cup pool. In the games they played against Leicester, I thought they played brilliantly," added Muller.

"Away from home after the first 20 minutes, they really came back and probably won the last 60 minutes of the game.

"Then at home against Leicester, they conceded a try in the 82nd minute to lose the game.

"The luck hasn't been on their side. If they had won those two games, they would be very close to being top of the pool right now."
