Quarterbacks under siege, with four sidelined

It was a rough day for NFL starting quarterbacks on Sunday.

Philadelphia’s Carson Wentz, Houston’s Tom Savage, the Jets’

Josh Mccown and Buffalo’s Nathan Peterman each left their respective games with injuries.

The most serious appears to be Wentz.

Two sources familiar with the injury tell The Associated Press that doctors believe Wentz has torn his left anterior cruciate ligament and will miss the rest of the season and playoffs. Wentz needs an MRI to confirm the severity of the injury.

Wentz was hurt late in the third quarter of Philadelphia’s comeback win at the Los Angeles Rams.

In Houston, Savage was cleared to re-enter the game against the San Francisco 49ers for one series after sustaining a concussion.

Savage was injured with about nine minutes remaining in the second quarter of Houston’s loss when he was driven to the ground on a hit by Elvis Dumervil. Replays showed Savage looking dazed after his head hit the ground with both of his arms shaking and lifted upward.

He was taken to the medical tent where he stayed for less than three minutes before returning to the bench and going back in for the next series. He threw two incompletions on that drive.

Coach Bill O’brien said he was evaluated for a concussion after the hit and cleared to return, but that he was evaluated again after he returned because “because of what they saw,” without providing details of what that was.

In snowy Buffalo, Peterman went 5 of 10 for 57 yards before being sidelined by a head injury late in the third quarter against Indianapolis. Peterman had started in place of Tyrod Taylor, who was sidelined by a bruised left knee in a loss to New England last weekend.

And Mccown left the game against Denver twice because of hard hits, including a clean shot by Shane Ray in the third quarter that left Mccown with a broken left hand. Mccown finished 6 of 12 for 46 yards.
