USC quarterbacks coach Clay Helton watched quarterback Tate Martell at Bishop Gorman High in Las Vegas on Monday.
"It was pretty cool having 2 of my top schools at my spring practice. #USC #TCU," Martell wrote on Twitter.
Martell is scheduled to visit USC's campus this weekend.
The 5-foot-10, 192-pound quarterback is a top recruit in the 2017 class. He has listed his top schools as USC, TCU, Texas A&M, Oregon and Notre Dame.
USC also has offered 2017 quarterback Tua Tagovailoa from Hawaii and Shawn Robinson, from Guyer (Texas), claims an offer.
