Jordan Mason's Stats, Metrics, Game Logs, Projections & Rankings

San Francisco 49ers running back Jordan Mason (ankle), who still hasn't been placed on Injured Reserve, was officially ruled out for the Week 14 game against the Chicago Bears this Sunday after missing practice all week. Mason suffered a high-ankle sprain in last Sunday night's loss to the Buffalo Bills and is expected to eventually land on IR, which would require him to miss at least four games. The 25-year-old will likely go on IR before the deadline on Saturday, which will make him eligible to return for the Week 18 regular-season finale against the division-rival Arizona Cardinals. With fantasy championships typically coming in Week 17, Mason should have already been dropped in redraft leagues. With Christian McCaffrey (knee) also done for the season, rookie Isaac Guerendo is now the 49ers' lead back, and he'll have immediate RB2 upside in his first NFL start this Sunday versus Chicago.

The San Francisco 49ers placed running back Jordan Mason (ankle) on Injured Reserve on Monday after he suffered a high-ankle sprain in the Sunday night loss to the Buffalo Bills. It means that Mason will miss at least the next four games and won't be eligible to return until the Week 18 regular-season finale on the road against the division-rival Arizona Cardinals. With fantasy championships typically coming in Week 17, managers now won't have a reason to hold onto Mason in single-year leagues. Christian McCaffrey (knee) also suffered a PCL injury in the snow on Sunday night and is facing a six-week recovery, so his season is likely over. It all means that fantasy managers in need at RB should make rookie Isaac Guerendo their top waiver-wire priority heading into Week 14. Guerendo should now lead San Fran's backfield, with Patrick Taylor also getting involved.

San Francisco 49ers running back Jordan Mason found some traction in an ugly 35-10 loss to the Bills in Orchard Park on Sunday night. The 25-year-old did most of his work after starter Christian McCaffrey (knee) left the game, finishing with 78 yards on 13 carries and no touchdowns. In a development that is sure to shake up fantasy leagues everywhere, McCaffrey's injury is feared to be significant, opening up championship hopes to those who held on to Mason through CMC's return. In six starts this year, Mason averaged 5.1 yards per carry and scored three touchdowns. Ahead of Week 14, fantasy managers in leagues where Mason is unclaimed should be prepared to break the bank on the waiver wire if McCaffrey is done for the year. Mason and the 49ers get the Chicago Bears at home next week, in a must-win against a vulnerable rush defense.
