Detroit Lions quarterback Matthew Stafford’s status for Week 15 is in doubt after injuring his ribs late in Sunday’s game, NFL Network reported Monday.

Further, there’s a possibility that the team shuts him down for the rest of the season (three games), according to the report. However, Stafford has not yet been ruled out of this week’s road game against the Tennessee Titans (9-4).

X-rays came back negative, Lions interim coach Darrell Bevell said Monday.

“This will be a deal where we take it to the end of the week,” Bevell said. “He’s a little bit better this afternoon than he was this morning so we’ll see how it goes and how he can progress.”

Stafford is in a great deal of pain, per the report.

Stafford was hurt after he scrambled for 6 yards and was tackled by Green Bay’s Kenny Clark in Sunday’s loss to the Packers.

He stayed in for the next play, a 2-yard touchdown run by Kerryon Johnson with 6:30 remaining, but came off the field holding his left side. Stafford didn’t return when the Lions next had the ball as backup Chase Daniel finished up the game.

Stafford twice went to the locker room for treatment, returning to the field on both occasions to lob some practice throws. After the second round of throws, he displayed visible discomfort that made it clear to Bevell that he couldn’t continue.

Stafford completed 24 of 34 passes for 244 yards and one touchdown before exiting.

Daniel was 3-of-6 passing for 29 yards in his second appearance for the Lions. He completed 8 of 13 passes for 94 yards, one touchdown and one interception against the Minnesota Vikings in Week 9 when Stafford departed to be evaluated for a possible concussion.

Stafford has passed for 3,522 yards and 22 touchdowns against nine interceptions this season.

If Daniel draws the start for the Lions (5-8), it will be the sixth of his 11-year NFL career.
