Running back David Johnson of the Arizona Cardinals was told he'd need surgery on his wrist after he dislocated it in Week 1 against the Detroit Lions. The 25-year-old chose to get a second opinion on whether surgery was necessary and apparently it is.

According to ESPN's Adam Schefter, Johnson is expected to be out two to three months following surgery on his wrist.

The loss of Johnson is a devastating blow to the Cardinals. Johnson is arguably among the elite running backs in the league today and without a doubt Arizona's best offensive weapon.

Before going down with the wrist injury on Sunday, Johnson rushed for 23 yards on 11 carries and had fumbled twice. Although ineffective running the football, Johnson was having a solid performance as a receiver with six catches for 68 yards. That catch total matched Larry Fitzgerald who finished with 74 yards receiving.

With Johnson placed on the injured reserve list, the Cardinals will likely turn to Kerwynn Williams to shoulder the load at the running back position. Williams scored the team's only rushing touchdown against the Lions while finishing with 10 yards on five carries.

The Cardinals reportedly signed Arizona State product D.J. Foster off the New England Patriots practice squad to help address the need at running back. There was talk of the team potentially bringing back Chris Johnson, but it's unclear whether that's still an option following the addition of Foster.

Last season, Johnson racked up a league-leading 2,118 yards from scrimmage to go along with 20 total touchdowns. The Cardinals running back earned Pro Bowl and All-Pro honors for his efforts.
