Who Should I Start? Jordan Mason or Tank Bigsby

Saturday, December 7, 12:22 PM

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.

Jacksonville Jaguars running back Tank Bigsby is a flex option at best in Week 16 against the Las Vegas Raiders. Bigsby was demoted to a backup role behind Travis Etienne Jr. in Week 15, making it hard to trust him in fantasy going forward. The Raiders do serve as a good matchup and potentially an unusually positive game script for the Jaguars, meaning both Bigsby and Etienne Jr. could get plenty of carries to succeed in fantasy. However, Mac Jones has been volatile at quarterback since replacing injured starter Trevor Lawrence, making it hard to trust the Jaguars offense as a whole. Given Bigsby can't be counted on for consistent volume, he is nothing more than a risky flex play despite a good matchup with the Raiders in Week 16.
