Miami Dolphins wide receiver David Boston will miss the season after injuring a tendon in his left knee during practice yesterday, Coach Dave Wannstedt said.

Wannstedt said the initial diagnosis was a strained patellar tendon, but an exam later yesterday in Houston revealed a more severe injury.

Boston, who is from the Houston area, was running a pass route when his left knee appeared to buckle during a workout against the Houston Texans.

"It is anticipated that the injury will require surgery that will sideline him for the season," Wannstedt said in a statement late yesterday. "Further details of his condition will be available following the conclusion of the surgery."

Boston's injury is the latest major blow to a franchise already without running back Ricky Williams, who retired just before training camp.

* FALCONS: Michael Vick doesn't understand all the fuss over his sore right hamstring. Neither does his new coach, Jim Mora Jr.

But they understand the concern Atlanta fans have about their star quarterback, who pulled the muscle on Thursday when the Falcons scrimmaged the Titans in Nashville.

"It makes it seem like I'm just getting dinged up and injuries are starting to come around a lot. I'll be fine, man," Vick said yesterday. "It's just small injuries there, just nagging injuries, things that happen in training camp. It's nothing severe, so I don't know why it's being made a big issue of it."

Mora agreed.

"I don't want it to be a situation where every time he gets dinged everyone thinks the sky is falling because it's not," he said.

Falcons fans can be forgiven for wincing every time Vick calls for a trainer. After breaking his right leg Aug. 16, he didn't play again until Nov. 30.

* BROWNS: Linebacker Brant Boyer is out indefinitely after breaking a bone in his right foot during practice. A team spokesman said Boyer was to have surgery later yesterday to have a screw inserted into the foot.

* RAMS: Defensive tackle Jimmy Kennedy, St. Louis's first-round draft pick a year ago, broke his right foot Thursday and could be out for the season. He was injured during a non-contact drill.

* SAINTS: Second-round pick Devery Henderson signed a four-year deal with the team, ending his holdout from training camp. Henderson, a wide receiver from LSU, practiced with New Orleans later in the day. In 2003, Henderson had 53 catches for 861 yards and 11 touchdowns.

* GIANTS: Linebacker Carlos Emmons missed his third straight practice because of pain in his left leg, the same one he broke late last season while playing with the Eagles.
