Making sure his O-linemen were happy for the holidays didn't come cheap for Kyler Murray ... 'cause TMZ Sports has learned the golf gifts he gave to his teammates this week cost $5K apiece!!!
The Arizona signal-caller shelled out the goodies to his personal protectors on Monday -- partnering with True Spec Golf to give them each a custom bag and custom clubs.
The package was sweet -- the bag featured every O-lineman's name and number and came complete with 13 total clubs -- including a driver, woods, hybrids, irons and wedges.
A rep for True Spec Golf tells us every players' clubs were properly fitted to them ... and in its entirety, the gift cost over $5,000 per bag.
Don't worry, the guys all appeared to love the presents from Murray ... smiling ear to ear while tagging balls at the True Spec Golf location in Scottsdale.
"It was a privilege to host Kyler Murray and his teammates at True Spec Golf," said the President of True Spec Golf, Ryan Richardson. "Similar to our everyday customers, some of the guys came in with years of experience and others were brand new to the game."
"It was great to show them how our data-driven, brand-agnostic approach at True Spec can improve anyone’s game regardless of skill level.”
At the moment, it's unclear if Murray -- who's previously gifted his O-linemen with scooters and paintings in the past -- will make this a yearly tradition, but we're told he will be coming back for a club fitting of his own following the season.
