Broncos: The largest crowd ever to watch a Denver practice didn't much like what it saw.

New quarterback Kyle Orton, acquired from Chicago for Pro Bowl passer Jay Cutler in the biggest NFL trade of the offseason, was booed by the crowd of 13,402 at his unofficial debut at Invesco Field when he threw two interceptions and several bad passes during a structured scrimmage last night.

Orton drew the fans' ire when he was picked off twice by cornerback Andre' Goodman, the second of which was returned for a long touchdown.

Orton also was jeered when he threw behind receiver Chad Jackson, again when he missed a wide-open Jabar Gaffney in the end zone and also when he floated a pass down the middle that Champ Bailey broke up.

"Fans can cheer. They can boo," Orton said. "We've got good fans, and they're passionate about their football, that's for sure."

Trade: The New England Patriots obtained defensive end Derrick Burgess yesterday after the two-time Pro Bowl player held out of the Oakland Raiders training camp in hopes of being traded.

The Patriots gave up undisclosed draft considerations for Burgess, who is coming off an injury-plagued season in which he had 3 1/2 sacks in 10 games.

Browns: Cleveland guard Rex Hadnot was carted off the practice field yesterday after suffering a possible serious injury to his left knee. The 6-foot-2, 320-pounder was engaged with defensive lineman Louis Leonard when rookie linebacker David Veikune, a University of Hawai'i alum, got pushed into the outside of Hadnot's left knee.

Steelers: Pittsburgh right guard Darnell Stapleton will have arthroscopic surgery on his left knee today and the team has no timetable set for his return. The 6-foot-3, 305-pound Stapleton had been practicing at center.

Chiefs: Kansas City has claimed quarterback Matt Gutierrez off waivers from New England. Gutierrez appeared in five games during two seasons with the Patriots, completing his only pass attempt for 15 yards.

Texans: Houston has signed free agent cornerback Deltha O'Neal and free agent running back Andre Hall, and released rookie defensive tackle Jake Visser and waived injured rookie running back Jeremiah Johnson.
