The sophomore two-way threat had that offer come from the Pac-12.
"UCLA offered Tyler today," said La Mirada head coach Mike Moschetti.
It was a quick turnaround for Luatua, who's film just made it to Westwood over the weekend.
"I sent his film to Demetrice Martin on Sunday night and Coach (Jim) Mora called me first thing on Monday morning and told me he was offering Tyler," said Moschetti.
The 6-4, 230-pounder can play a multitude of positions.
"He's a physical freak," said Moschetti. "He can play tight end, defensive end, receiver or linebacker."
Luatua's older brother, Isaac, redshirted this past season at Alabama, where the Tide won the BCS National Championship.
"He's a totally different player than Isaac is," said Moschetti. "Isaac was a lineman but Tyler can play both sides and is a better athlete."
Luatua had 23 receptions for 251 yards and a touchdown this past season as a sophomore.
