Previously, SBS revealed that nothing was yet certain about Lee Jong Suk joining 'Running Man' as planned due to his sudden contraction of the swine flu on the 18th. However, while things continue to be up in the air, it seems there is still a chance that Lee Jong Suk might join them later on in the middle of filming.

The cast and crew are preparing to leave for Australia on February 22 as planned. However, Lee Jong Suk will be unable to leave with them at the moment.

One show rep told OSEN on February 21, "Tomorrow, the 'Running Man' team will leave the country through Incheon Airport, but Lee Jong Suk told us he will confirm his appearance after watching over his health condition a little longer. �There is a possibility that he will join us in the middle."

Hopefully, he gets all the rest that he needs to make a full recovery. Although it'd be a bonus if he makes recovery to join in on partially filming for the show, as fans are probably eager to see him with Rain and especially Kim Woo Bin, his health should always come first!�
