Report: 49ers RB Jordan Mason gets good news on shoulder injury

A Jordan Mason update with good news:

The San Francisco 49ers and running back Jordan Mason may have avoided a disaster.

Mason injured his shoulder in the second quarter of the 49ers’ Week 6 win over the Seattle Seahawks. He returned for the second half, but exited after aggravating the shoulder on the first play of the third quarter. He spent the remainder of the game on the sideline and head coach Kyle Shanahan didn’t have much information after the game.

ESPN’s Adam Schefter on Friday morning reported the injury is believed to be an AC joint sprain that isn’t considered serious. Mason will undergo further testing Friday.

Head coach Kyle Shanahan will speak with reporters Friday afternoon and may have a further update on the 49ers’ breakout star.

If the 49ers can manage to avoid anything major with Mason it would be a significant win for them given the impact he’s had on their offense. Their run game struggled without him in Seattle, save for rookie RB Isaac Guerendo’s game-sealing 76-yard run. Guerendo would be Mason’s replacement if he’s unable to suit up in Week 7 vs. the Chiefs.

Mason finished Thursday’s game with 73 yards on nine carries. He also ripped off a 38-yard run in the game, marking his longest rush of the season.

After Week 6 he’s up to an NFL-best 609 yards on an NFL-high 114 carries.
