Griffin, backing up Bilal Powell, was yanked to the ground in the third quarter on a horse-collar tackle by LB Travis Lewis. Griffin was carted to the locker room, where an X-ray confirmed the fracture.
He was on the roster bubble, but at least he was an able body. The Jets are hurting at the position. Chris Ivory (hamstring) and Joe McKnight (head) didn't travel to the game, and Mike Goodson still hasn't reported to camp because of undisclosed personal reasons. Ivory is expected to practice for the first time Sunday.
The Jets' running attack was non-existent, as they ran for only 37 yards on 16 carries.
INJURY REPORT: Aside from Griffin, QB Geno Smith (ankle) and OLB Garrett McIntyre (knee) left with injuries. Smith's injury doesn't appear serious. He said he told the trainers that he wants to practice next week and play next Saturday against the Jaguars.
UNHAPPY REX: A subdued Rex Ryan bemoaned a rash of mistakes -- 11 penalties, two turnovers, a poor rushing attack and sloppy play by the second-team defense.
"We have to improve a great deal," he said.
It was a particularly sloppy day for the offensive line. RG Willie Colon was called for holding and a false start and LG Stephen Peterman, a former Lion, was flagged for holding. Backup OT Oday Aboushi was guilty of a false start.
Ryan singled out only two players for exceptional performances -- WR Ben Obomanu (team-high four catches) and S Jaiquawn Jarrett (five tackles, one QB hit). Ryan said Jarrett will move up to the first team in practice next week, replacing Antonio Allen.
SPECIAL K: It was a nice debut for TE Kellen Winslow, trying to resurrect his career after a lost 2012. He caught two passes for 30 yards, including a 24-yard reception that helped set up the first touchdown. He caught a short pass and broke a tackle, displaying some of the old Winslow.
He was cut by the Seahawks last preseason and played only one game with the Patriots.
"That was their loss," he said of the Seahawks. "I'm going to do some things this year."
ODDS AND ENDS: Rookie CB Dee Milliner received mixed reviews. "At times, I thought he played really well," Ryan said. But there was a missed tackle in the open field, a 27-yard completion against him and a couple of mentor errors. ... DT Sheldon Richardson, who was credited with three tackles, said he didn't make as many plays as he had hoped. ... Rookie WR Zach Rogers had a bad drop in the open field, but he came back to score on an 11-yard pass from Greg McElroy. ... McElroy, one of the stars of last week's scrimmage, delivered another fine outing. He replaced the injured Smith in the third quarter and was 11-for-19, 145 yards and a touchdown. ... Nick Folk made a 51-yard FG. ... Muhammad Wilkerson and Quinton Coples recorded sacks. Coples cleaned up after LB Antwan Barnes made the key pressure.
