When Notre Dame defeated North Carolina in Chapel Hill last weekend, it apparently had an impact on the Dallas Mavericks’ locker room dynamics.

On Wednesday, two former North Carolina players — Reggie Bullock and Theo Pinson — showed up to practice donning Notre Dame green.

Here’s a look:

The bet was seemingly with Mavericks assistant coach Sean Sweeney, who is a noted Notre Dame football fan. Here’s a clip of Pinson trying to explain the situation:

Coach Marcus Freeman, who visited the Mavs and Sweeney earlier this offseason, acknowledged the situation on Thursday morning:

Notre Dame is now 2-2 on the season and has seemingly rebounded from a pair of tough losses to start the year. Quarterback Drew Pyne had his best start of the year vs. UNC, throwing for 3 touchdowns in the win.

The Fighting Irish are off in Week 5 but will face BYU in a neutral site game in Las Vegas in Week 6.
