San Francisco 49ers ...San Francisco 49ers running back Jordan Mason (shoulder) is believed to have suffered a sprained AC joint during Thursday's night game, according to Adam Schefter of ESPN. Schefter further noted that the 25-year-old will undergo further testing later on Friday. Mason left Thursday's game in the first half and was only able to see one rushing attempt during the entire second half due to the injury. This opened the door for fourth-round rookie Isaac Guerendo to see a season-high 10 carries for 99 yards. Fantasy managers should continue to monitor Mason's status ahead of their Week 7 matchup against the Kansas City Chiefs. If Mason were to miss an extended period of time, Guerendo becomes a priority waiver-wire target and a must-start option.
