A caster has two choices; cast or cast defensively. In the former, the caster takes the attack of opportunity and makes the concentration check based on any damage received to keep the spell. In the latter, the caster makes a concentration check to alter the casting to avoid becoming vulnerable to an attack of opportunity. Since the latter wasn't stated OOC, I assume the former is the operative situation here.
