NFL notes: Ben Roethlisberger injures left knee, Steelers wait on MRI

The Steelers will wait for results of an MRI on Ben Roethlisberger’s left knee after the three-time Pro Bowl quarterback was carted off the field in the third quarter of Sunday’s 12-6 win at St. Louis.

Michael Vick replaced Roethlisberger, who was hurt when his leg was caught underneath him on a diving, sliding sack by Mark Barron. Big Ben left the stadium on crutches and wearing a bulky brace.

Roethlisberger hasn’t missed a start since 2012, when he was out for three games late in the season because of a shoulder injury. Vick completed 5 of 6 passes for 38 yards in relief.

The Steelers (2-1) host the Baltimore Ravens (0-3) on Thursday night.

In other injury news:

• Jets CB Darrell Revis tweaked his hamstring. Revis started the game despite being questionable because of a groin injury.

• Vikings CB Xavier Rhodes suffered a head injury in a scary collision with teammate Andrew Sendejo.

Brady throws 400th TD

Patriots QB Tom Brady threw his 400th career touchdown pass, hitting Danny Amendola on a 1-yard pass just before halftime of the Patriots game against Jacksonville.

Brady joins Peyton Manning (533 entering Sunday), B rett Favre (508) and Dan Marino (420) as the only quarterbacks in NFL history to reach the milestone.

Newton can’t get a call

Cam Newton was a little miffed at what he said were comments from referee Ed Hochuli during the Panthers’ win over the Saints. Newton was upset over what he felt was a borderline late hit by Saints DT Tyeler Davison – but was even more baffled by the explanation he said he received from Hochuli.

“The response that I got was, ‘Cam you’re not old enough to get that call,’ ” Newton said after the game. “I’m looking at him like, ‘What?’ ”
