LAS VEGAS >> Not every athlete is caught up in the Linsanity.

Unbeaten boxer Floyd Mayweather Jr. has posted a swipe at the New York Knicks’ point guard sensation on Twitter.

Mayweather posted on Monday: “Jeremy Lin is a good player but all the hype is because he’s Asian. Black players do what he does every night and don’t get the same praise.”

Lin has led the Knicks to five straight victories, including a 38-point game against the Lakers.

Mayweather rarely hesitates to air racially charged opinions, either in person or in social media.

He has repeatedly insulted rival Manny Pacquiao, including an online video in 2010 in which he used racial and homophobic slurs against the Filipino champion.

Leonard Ellerbe, Mayweather’s top adviser, didn’t immediately return a phone call.
