After if, we use the present (not will). We say 'ifyou see ... ' (not ifyou will see):

0 If you see Ann tomorrow, can you ask her to call me?

0 If I'm late this evening, don't wait for me. (not if I will be)

0 What shall we do if it rains? (not if it will rain)

0 If I don't feel well t omorrow, I'll stay at home.
