Recruiting Rules Question

Lets say I have this friend... he has been friends with a coworker for 3 years now. His coworkers son happens to have developed into a fine HS football player (jr). The coworker is a fan of TCU and my friend an SMU fan. Naturally they wanted to see the game together this weekend and he wanted to invite both the coworker and son since he has two extra tickets. How is that viewed?
