"Concerned" Australian Davis Cup captain Lleyton Hewitt is waiting with interest to see how Bernard Tomic shapes up on Tuesday in his opening match of the summer.

Overlooked by Hewitt for an Australian Open wildcard after snubbing last month's wildcard playoff and then withdrawing from the Brisbane International, Tomic will finally surface at the Kooyong Classic exhibition event.

The fallen star will play a best-of-three-sets Fast4 match against Yoshihito Nishioka as a precursor to his appearance on Wednesday in Open qualifying.

Asked if he was pleased Tomic was attempting to qualify, Hewitt didn't appear overly convinced.
