Former Green Bay Packers safety LeRoy Butler had a speaking engagement at a Wisconsin church apparently canceled, according to the Milwaukee Journal Sentinel, after he sent a message of support for NBA player Jason Collins, who announced this week that he is gay.After sending a four-word message on Twitter — “Congrats to Jason Collins” — Butler got a call from a member of the church where he was to give an anti-bullying presentation this summer. Butler was told the church would cancel his presentation unless he removed the tweet, apologized and asked for God’s forgiveness.“They said, ‘If you ask for forgiveness and remove the tweet and you say something to the effect that you don’t congratulate [Collins], then we’ll let you do the engagement and get the speaker’s fee [of $8,500],’ and I said I’m not doing that,” Butler said.Butler told the church’s pastor that this “form of bullying” was an example of the kind of treatment he had planned to talk about at the church.Briefly • Seahawks: McMurry University quarterback Jake Mullin, a Burleson High School graduate, has been invited to a tryout during the team’s rookie minicamp May 10-12.
