Cardinals RB David Johnson avoids broken wrist but will undergo MRI on Monday

DETROIT -- Arizona Cardinals RB David Johnson did not break his wrist in his team's 35-23 loss to the Lions, and the team believes the injury is a "bad sprain," ESPN's Adam Schefter reports. Johnson will undergo an MRI on Monday.

A source told ESPN's Chris Mortensen that Monday's MRI will determine whether Johnson misses a "few weeks" or "half the season or more," in a worst-case scenario.

Johnson appeared to have hurt his wrist after a 24-yard catch in the third quarter, but Arians said the injury happened when Johnson fumbled the ball on the only play of Arizona's next drive. Johnson left the game and did not return.

"We'll find out the severity of that," Arians said after the game.

The results of Johnson's X-rays came back negative, a source told ESPN, confirming a report by Pro Football Talk. Arians declined to confirm the report.

"I don't know anything about X-rays yet," he said.

Johnson struggled to get going all game. He finished with 23 rushing yards on 11 carries and six receptions for 68 yards, giving him 91 yards from scrimmage. He started the previous season with more than 100 yards from scrimmage in his first 15 games.

This is the second straight game in which Johnson suffered an injury. He left the season finale in January with a sprained MCL.
