Report: Cowboys FB Ryan Nall to miss 2-4 weeks

Dallas Cowboys fullback Ryan Nall will miss 2-to-4 weeks with a deep shoulder contusion, the Dallas Morning News reported Thursday.

Nall, 26, was the only healthy fullback on the 90-man roster. The Cowboys used guard Connor McGovern as a lead blocker at training camp on Thursday, per the report.

Nall signed a one-year, $965,000 deal with Dallas in March.

Used nearly exclusively as a lead blocker in the offense, Nall played in 33 games for the Chicago Bears the past three seasons. He has nine career catches for 71 yards and a touchdown to go with 12 career rushing yards.

Nall also played 577 snaps on special teams in three seasons with the Bears.
