PHOENIX - The fight over Arizona's immigration law showed no signs of letting up Friday as the federal judge who blunted its force faced threats and the Republican governor who signed it considered changes to address any faults.

In the days since U.S. District Judge Susan Bolton put on hold the most controversial parts of the law, hundreds of e-mails and phone calls - including some threats - have poured into the courthouse.

And a fund set up to help defend the new law added $75,000 Wednesday alone, giving the state more than $1.6 million to get Bolton's ruling overturned.

ENGLEWOOD, Colo. - Tim Tebow is ready for the shots, both on the football field and in the locker room.

The two-time national champion from Florida practiced with other rookies Friday in advance of the start of the Denver Broncos' training camp and said he couldn't wait for the hard hits.

Tebow, the 25th pick in the NFL draft, is fresh off putting his signature on two contracts, one of them a five-year deal to play for the Broncos and the other a multiyear deal to serve as a pitchman for Jockey underwear.
