Substitute rule for College Soccer?

[El Paso Eagle]

Can someone help me understand the substitution rules in college soccer? Thanks.

1st half: no re-entry after substitution for duration of 1st half; may re-enter at start of 2nd half

2nd half: can re-enter game 1 time after a SECOND HALF substitution.

College rules are different from Pro level.  In Pros, once removed from game cannot return.

Hope this helps.

Thank you. I was curious as well.
