Butler is one of Creighton's top rivals in the Big East, but the Bulldogs set that aside to send a note of support to Maurice Watson.
The injured Bluejay tweeted a picture Thursday of a note he received from the Butler team wishing him a speedy recovery from his torn ACL. The card was also signed by the entire team.
"We were all saddened to learn about your knee injury. You were such a tough player to prepare for and one heck of a competitor. The league will miss having you in it. We wish you all the best in a speedy recovery."
Watson responded: "Much respect to (Butler) for sending me a card and the entire team signing it! Makes it mean more knowing all the tough battles we had!"
No. 22 Creighton defeated No. 16 Butler on Tuesday, the Bluejays' fourth victory this season over a Top 25 team.
Watson also appeared on "The Bottom Line" Thursday. Click here to watch the full video from that interview.
