Cornerback Leon Hall slipped past the receiver and closed in on running back BenJarvus Green-Ellis, lowering his shoulder slightly as he approached.

He pulled up at the last moment — it was a non-contact drill — but was right where he wanted to be in one of the first workouts of training camp. Fully healed from a significant injury, Hall is ready to resume his role at the Cincinnati Bengals’ best cornerback.

Hall reclaimed his spot on the starting defense for the first practice of camp on Friday, a very encouraging sign for a team that really needs him. He had no problem with his left Achilles’ tendon, which he tore Nov. 13.

“I felt rusty for sure, but the Achilles felt fine,” he said, heading off the grass practice field. “I was able to move and cut and break, but my technique needs work.”

While Hall ran around the field, top draft pick Dre Kirkpatrick rode a stationary bike or watched from the sideline, two orange gloves dangling from his waist. The cornerback from Alabama hurt his left knee while working out apart from the team and isn’t ready to practice.

Brown gets 5 more years

The Pittsburgh Steelers signed wide receiver Antonio Brown to a five-year extension that will keep him with the team through the 2017 season.

Brown, voted Pittsburgh’s most valuable player by teammates last season, was entering the final season of the three-year contract he signed when he was drafted out of Central Michigan in 2010. CBS Sports first reported the deal that will earn Brown $42 million over the next six seasons.

Heat sidelines Bills rookie

Buffalo Bills cornerback Leodis McKelvin missed the final hour of practice after being escorted into a cooling tent because he felt ill.

Coach Chan Gailey said the player was taken into the tent as a precaution and held out for the rest of the two-hour session Friday, two days into training camp.

With a wet towel on his head, McKelvin walked without assistance while being escorted off the field by a trainer. The mid-afternoon practice was held under a mostly cloud-less sky with temperatures in the low 80s.

Concussion shelves Best

Detroit Lions running back Jahvid Best has been put on the active physically unable to perform list.

Best didn’t play last season after a concussion suffered in a game against San Francisco on Oct. 16. He also had concussion problems last preseason and when he was a college player at California.

Best started nine games for the Lions as a rookie in 2010 and rushed for 390 yards on 84 carries last season.

Detroit has also put offensive lineman Jonathan Scott on the active non-football injury list.

Panthers add linebacker

The Carolina Panthers signed free-agent linebacker David Nixon. He replaces running back Armond Smith, who was waived a day before the Panthers announced Nixon’s signing Friday.

Nixon participated in Carolina’s three-day rookie minicamp as an invited tryout player in May. He’s played for three different teams since joining the NFL as an undrafted rookie out of Brigham Young in 2009.

Talley accused in fracas

Arizona Cardinals defensive end Ronald Talley is accused of smashing a champagne bottle on the head of a man at a bar near Detroit. Robert Ford, 30, of Detroit was attacked near the restroom of the South Bar in Birmingham on March 26 and dragged to the alley by bouncers, according to a lawsuit filed Wednesday in Oakland County Circuit Court against Talley and unnamed bouncers.
